Temporary pacing wires are often used following cardiac surgery to optimise the heart rhythm. Although setting and checking temporary pacemakers is typically undertaken by anaesthetists, intensivists, and nursing staff who care for post-cardiac surgical patients, almost all patients with temporary pacing wires are transferred to the ward with the pacing wires left in situ, where surgical, often junior, staff become responsible for temporary pacing wire management. Thus, knowledge is required not only of temporary pacing wire indications, types, and positioning at surgery, but also of practical skills in performing a pacing check, setting the pacemaker, and troubleshooting common problems...

Unlimited access to ECGs using an over-the-counter smartwatch constitutes a real revolution for our discipline, and the application is rapidly expanding to include patients with cardiac implantable electronic devices (CIEDs) such as pacemakers (PMs) and implantable cardioverter defibrillators (ICDs). CIEDs require periodic evaluation and adjustment by healthcare professionals. In addition, implanted patients often present with symptoms that may be related to their PMs or ICDs. An ECG smartwatch could reveal information about device functioning, confirm normal device function, or aid in the case of device troubleshooting...

Temporary epicardial cardiac pacing in patients with bradyarrhythmias may be used as a bridge to implantation of a permanent pacemaker. The temporary epicardial lead placement may sometimes necessitate a sternotomy that may pose a challenge in patients who have had multiple earlier sternotomies. The difficulty in accessing the epicardium for urgent implantation of temporary epicardial pacing leads depends on the extent of adhesions in such patients. We report an 8-year-8-month-old girl with a pacemaker with an extruded pulse generator and difficult myocardial access due to 5 prior transsternal procedures...

BACKGROUND: The Heart Rhythm Society strongly recommends remote monitoring (RM) of cardiovascular implantable electronic devices (CIEDs) because of the clinical outcome benefits to patients. However, many patients do not adhere to RM and, thus, do not achieve these benefits. There has been limited study of patient-level barriers and facilitators to RM adherence; understanding patient perspectives is essential to developing solutions to improve adherence. OBJECTIVE: We sought to identify barriers and facilitators associated with adherence to RM among veterans with CIEDs followed by the Veterans Health Administration...

INTRODUCTION: Leadless cardiac pacemakers are an alternative modality to traditional transvenous pacemaker systems. Recently receiving Food and Drug Administration approval, the AVEIR VR leadless pacemaker system provides a helix based active fixation leadless pacemaker system. This step-by-step review will cover patient selection, preprocedural planning, device implantation technique, implant site evaluation, troubleshooting, short- and long-term complications as well as future directions for leadless pacing...

Circadian clocks drive cyclic variations in many aspects of physiology, but some daily variations are evoked by periodic changes in the environment or sleep-wake state and associated behaviors, such as changes in posture, light levels, fasting or eating, rest or activity and social interactions; thus, it is often important to quantify the relative contributions of these factors. Yet, circadian rhythms and these evoked effects cannot be separated under typical 24-h day conditions, because circadian phase and the length of time awake or asleep co-vary...

BACKGROUND: The Nanostim leadless pacemaker (LP) was launched in 2012. However, the use of Nanostim LP was suspended due to safety. OBJECTIVE: The aim of this study was to report our experience with the management of malfunctioning Nanostim LPs, including premature battery depletion. METHODS: Fifty-one consecutive patients (age 83 ± 10, 65% male) who underwent Nanostim LP implantation between 2014 and 2016 at Isala Hospital s were identified...

Numerous patients with a cardiac implantable electronic device are admitted to the cardiac intensive care unit (ICU). When taking care of these patients, it is essential to have basic knowledge of potential device problems and how they could be tackled. This review summarizes common issues with pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization devices and provides a framework for troubleshooting in the ICU. In addition, specific aspects of intensive care that might interfere with cardiac devices are discussed...

Pacemaker-troubleshooting is an important step in the evaluation of a patient with syncope post-pacemaker-implantation. The basic functions of sensing, pacing and impedance may remain spuriously normal in the case of lead-microfracture or insulation break. We report a case in which the lead dysfunction was diagnosed based on multiple episodes of premature ventricular beats.

Normal function and the most common problems that occur during pacemaker operation while performing physical exercise, are discussed. Physically active individuals with an implantable cardiac device, should be evaluated during exercise, because some conflicts issues may arise that are not detectable during routine, at rest, telemetry.

The indications for permanent pacemaker (PM) implantation are rapidly expanding resulting in an increasing number of patients receiving PMs. Such PM patients need a good quality medical care. The follow up of these patients and their devices places a heavy burden on cardiology clinics with significant implications for the already stretched hospital resources. This has resulted in increased reliance on the options of automatic and continuous adjustments that the modern PMs offer. One such feature is the 'automatic sensitivity function' or 'AutoSense' which when turned on, monitors the amplitude of the intrinsic R wave and P wave and continuously adjusts the sensitivity, as a function of measured amplitudes, to avoid undersensing or oversensing...

Far-field R wave (FFRW) oversensing in atrial channel is known to cause inappropriate automatic mode switch. We describe a case of 63-year-old lady with dual-chamber permanent pacemaker implanted 2 years back for symptomatic infra-hisian complete heart block and normal biventricular function. After 6 months, she underwent upgradation to cardiac resynchronization therapy (CRT-P, Boston Scientific) for right ventricular pacing induced cardiomyopathy. Her LV function normalized after CRT. Later on, FFRW oversensing caused false triggering of an atrial tachycardia, which subsequently opened up an "atrial flutter response" window leading to symptomatic inadvertent atrioventricular block at frequent intervals...

An infant with congenital heart block and hemodynamically significant bradycardia underwent therapeutic temporary pacing wires placement. Post-operatively, frequent "asystole" alarms were observed on telemetry causing distress to both the family and the nursing staff. Investigation of these alarms showed that pacemaker malfunction led to monitor pseudo-malfunction. The alarms were alleviated with mindful setting of the pacemaker and telemetry monitor parameters. This case highlights the challenges of pacemaker placement and monitoring of very small infants in the intensive care setting...

Micra leadless pacemaker has progressed from a single chamber pacemaker that can deliver VVIR pacing to a pacing device that can provide atrio-ventricular (AV) synchrony via a unique pacing algorithm that relies on identifying mechanical atrial contraction. This novel algorithm has its own limitations and intricacies. In this paper, we review this algorithm, suggest steps for troubleshooting and programming these devices and provide clinical examples of Micra AV cases that required changes in programming for adequate tracking of atrial activity...

The event of repetitive nonreentrant ventriculoatrial synchrony (RNRVAS) and its course of cardiac device management has been authenticated. However, this context has not been well-documented in the presence of high-degree antegrade heart block. This case report will discuss the challenges of treatment in this subgroup of patients.

We describe a case of a 65-year-old gentleman with nonischemic cardiomyopathy and left bundle branch block who underwent cardiac resynchronization therapy device. After becoming a responder initially, he experienced significant clinical worsening on follow-up. Device interrogation revealed several long episodes of inappropriate automatic mode switch (AMS) entry due to far-field R wave oversensing resulting in loss of atrioventricular synchrony. Moreover, pacing in VVI mode with consistent VA conduction taking place during the AMS episodes was also found to be detrimental, which helped in sustaining the episodes and produced pacemaker syndrome like phenomenon...
