The AV-reentrant tachycardia (AVRT) is a supraventricular tachycardia with an incidence of 1-3/1000. The pathophysiological basis is an accessory atrioventricular pathway (AP). Patients with AVRT typically present with palpitations, an on-off characteristic, anxiety, dyspnea, and polyuria. This type of tachycardia may often be terminated by vagal maneuvers. Although the clinical presentation of AVRT is quite similar to AV-nodal reentrant tachycardias, the correct diagnosis is often facilitated by analyzing a standard 12-lead ECG at normal heart rate showing ventricular preexcitation...

The scope of application for implantable loop recorders has shifted away from the evaluation of unclear palpitations and syncope episodes to more complex conditions. This article focuses on rare indications of growing importance such as rhythm monitoring after ablation of atrial fibrillation or after cryptogenic stroke. Furthermore, forthcoming applications in various clinical settings are described, e. g., arrhythmia detection after myocardial infarction, after catheter-based valve interventions, in heart failure, and in cardiomyopathies...

The implantable loop recorder BioMonitor 2 is available with an emphasis on syncope and one on detection of atrial tachycardias. The BioMonitor 2 can be easily implanted. The BioMonitor 2 pilot study showed a high and over time stable signal and the telemetric performance was above average.

It was proven in multiple studies that about 30 % of cryptogenic strokes are related to clinically silent atrial fibrillation (AF). There is an opportunity for prolonged ECG monitoring mainly through an implanted event recorder after completion of conventional diagnostic methods in an unidentified stroke source. The Crystal AF study has proven, together with other results, improved AF detection through prolonged monitoring for up to 36 months. An implanted event recorder for 2-3 years is suitable for this particular purpose...

INTRODUCTION: Patients with advanced heart failure suffer from frequent hospitalizations. Non-invasive hemodynamic telemonitoring for assessment of ventricular filling pressure has been shown to reduce hospitalizations. We report on the right ventricular (RVP), the pulmonary artery (PAP) and the left atrial pressure (LAP) sensor for non-invasive assessment of the ventricular filling pressure. METHODS: A literature search concerning the available implantable pressure sensors for noninvasive haemodynamic telemonitoring in patients with advanced heart failure was performed...

INTRODUCTION: We describe the case of a 78-year-old patient who presented for ablation of a wide complex tachycardia with right bundle branch block (RBBB) morphology. A pacemaker spike at the QRS onset indicated supraventricular tachycardia with AV synchronous ventricular pacemaker activation. METHODS: Correct positioning of the ventricular lead in the right ventricular apex was confirmed by fluoroscopy and echocardiography, excluding malpositioning of the right ventricular lead...

Implantable loop recorders (ILR) do not play a pivotal role in the current guidelines on ventricular arrhythmias except in identifying rhythm-symptom correlations if ventricular arrhythmias are assumed. Before a decision for a pure diagnostic implantable device is made, a thorough arrhythmic risk assessment is of major importance due to the potential lethal outcome of ventricular arrhythmias. Nevertheless, some clinical circumstances exist where long-term monitoring by an ILR may add significant information in electrical heart diseases, in patients with ventricular arrhythmias, or structural heart diseases and a potential risk of ventricular arrhythmias...

BACKGROUND: Implantable loop recorders (ILR) are an established diagnostic method for detection of cardiac arrhythmias including atrial fibrillation. OBJECTIVE: The aim of this work is to provide an overview of available data and indications of ILR in atrial fibrillation, especially after catheter ablation, in order to illustrate practice-oriented recommendations. MATERIALS AND METHODS: We conducted a selective PubMed literature search. RESULTS AND DISCUSSION: ILR can record asymptomatic/rare atrial fibrillation episodes and prevent thromboembolic events by allowing timely initiation of oral anticoagulation...

St. Jude Medical produces the implantable loop recorder (ILR) Confirm AF DM2102 which offers subcutaneous electrodes on both sides of the device, a specific sensing algorithm and extensive storage capacity for up to 147 episodes. The reliability of detection of atrial fibrillation (AF) has been evaluated in the DETECT-AF study. The device is MR-conditional and allows patients an interrogation at home. The data are transferred to the follow-up centre via telephone by the patient activator, although this process is currently rather complex and slow...

In syncope patients, it is essential to make the right diagnosis with respect to underlying etiology. Cardiac (arrhythmic and structural) syncopal episodes carry untoward prognostic implication compared with reflex syncope. While rhythm-symptom correlation of a spontaneous syncopal episode is key to making the correct diagnosis, in case of unclear syncope the early implantation of a loop recorder leads to faster, more efficacious, and more cost-effective diagnosis. This review article summarizes the current data regarding diagnostic accuracy and clinical role of implantable loop recorders...

Andreas Schuchert
Increasing complexity and many technical solutions for cardiovascular devices make it reasonable to introduce an advanced classification. The proposed classification has three levels. The first level distinguishes between implantable and wearable devices and the second level between therapeutic and diagnostic devices. The third level describes group-specific characteristics for each of the four subgroups. The aim of the classification is to differentiate the devices from each other and to easily describe interactions between two or more different devices...

BACKGROUND: Little is known about the incidence and risk factors for progression to pacemaker dependency or the need for cardiac resynchronization in typical patients with an implanted defibrillator with regard to an alternative implantation of a subcutaneous ICD (S-ICD). STUDY DESIGN AND METHODS: After retrospective analysis of 291 patients with first implantation of a transvenous single chamber ICD (VVI-ICD) from 2010-2016 and excluding those with an indication for pacemaker or lack of follow-up data, 121 patients were included and investigated with regard to the following endpoints: need for pacemaker stimulation, upgrade for cardiac resynchronization (CRT), and secondary occurrence and effectiveness of antitachycardia pacing (ATP)...

Claudia Schaarschmidt, Christof Kolb
The subcutaneous implantable defibrillator (S-ICD) has become an established tool for the prevention of sudden cardiac death. Based on its detection properties, the S‑ICD is essentially dependent on correct morphology discrimination of the QRS complex and avoidance of potential T‑wave sensing. We report on a patient who experienced multiple inappropriate S‑ICD shocks due to T‑wave oversensing in the setting of new onset of right bundle branch block. Strategies for the optimisation of the device programming are discussed...

Persistent left superior vena cava is known to be a challenging anatomic abnormality for transvenous cardiac device implantation. In the a case of a young man presenting with dilative cardiomyopathy with severely impaired left ventricular ejection fraction (LVEF) and second-degree atrioventricular block (AV block), cardiac resynchronization therapy (CRT) with defibrillator (CRT-D) implantation was indicated. A transvenous approach was attempted, but placement of the right ventricular lead was not successful due to anatomic abnormalities...
