BACKGROUND: General anesthesia dramatically decreases the activity of the autonomic nervous system. Most of the hypnotic agents used to induce anesthesia inhibit sympathetic cardiovascular regulation and baroreflex control in a dose-dependent manner, lowering cardiac adaptability during the operation. The consequence of this effect in children during and after surgery has never been studied to date. AIM: The aim of this study was to follow the variations in autonomic cardiac indices in children younger than 8 years old after general anesthesia (6-24 hours) in programmed surgery...

In an 86-year-old woman who had been treated for sick sinus syndrome, the small high-frequency current delivered by pacemaker in order to measure the minutes ventilation for utilizing the rate-response mode was transiently over-sensed on the Holter electrocardiogram. Although her pacing system was working appropriately, the numbers of the paced beats on the automatic Holter analysis were undercounted (from >60% to <5%) during the over-sensing periods because these currents were recognized as multiple pacing spikes...

OBJECTIVE: We tested whether ablation methodology and study design can explain the varying outcomes in terms of AF-free survival at 1 year. BACKGROUND: There have been numerous paroxysmal AF ablation trials, which are heterogeneous in their use of different ablation techniques and study design. A useful approach to understanding how these factors influence outcome is to dismantle the trials into individual arms and reconstitute them as a large meta-regression. METHODS: Data was collected from 66 studies (6941 patients)...

CLINICAL INTRODUCTION: A 52-year-old woman with shortness of breath and palpitations was referred to a cardiologist. A 24-hour Holter demonstrated high density (37%) of ventricular premature beats (VPBs) and long runs of non-sustained (eventually sustained) monomorphic ventricular tachycardia (VT) with the same morphology as several VPBs detected in a 12-lead ECG (figure 1A). A transthoracic echocardiogram was performed, and the patient's evaluation was completed with a functional and gadolinium-enhanced cardiovascular MR (CMR) study (figure 1B,C) to assess structural heart disease...

OBJECTIVE: Micro T-wave alternans (MTWA) has been associated with poor arrhythmic prognosis in various cardiac disorders. The aim of this study was to assess the relationship between the presence of MTWA and the predicted 5-year risk of sudden cardiac death (HCM Risk-SCD) among patients with hypertrophic cardiomyopathy (HCM). METHODS: A total of 117 consecutive HCM patients were included in this prospective observational study. Patients were divided into two groups, according to the presence [MTWA (+) group (n=44)] or absence [MTWA (-) group (n=73)] of MTWA on ambulatory (Holter) electrocardiography...

INTRODUCTION: Several clinical scoring systems have been derived to predict the arrhythmia outcome of catheter ablation (CA) for atrial fibrillation (AF) but which is better is not clear. Simple clinical risk scores (that any clinician can use in the everyday clinic) can help assess the likelihood of recurrence of AF following CA and the simple MB-LATER score has recently been described. We compare the predictive ability of seven existing clinical scoring systems (HATCH, CHADS2 , CHA2 DS2 -VASc, BASE-AF2 , APPLE, CAAP-AF, and MB-LATER) in a Chinese cohort of AF patients undergoing CA...

Background: Idiopathic outflow tract ventricular premature contraction (VPC) can evolve into ventricular tachycardia (VT) via triggered activity mechanism. Transmural dispersion of repolarization (TDR) might play a role in idiopathic outflow tract VT by inducing phase 2 early afterdepolarization (EAD) and serve as the functional substrate for VT. Tp-Te/QT ratio as an arrhythmogenesis index has been reported to be associated with the incidence of ventricular arrhythmia. This study aims to investigate the association between Tp-Te/QT ratio with VT incidence in idiopathic outflow tract VPC...

The automated detection of arrhythmia in a Holter ECG signal is a challenging task due to its complex clinical content and data quantity. It is also challenging due to the fact that Holter ECG is usually affected by noise. Such noise may be the result of the regular activity of patients using the Holter ECG-partially unplugged electrodes, short-time disconnections due to movement, or disturbances caused by electric devices or infrastructure. Furthermore, regular patient activities such as movement also affect the ECG signals and, in connection with artificial noise, may render the ECG non-readable or may lead to misinterpretation of the ECG...

BACKGROUND: Patient prognosis in type 1 myotonic dystrophy (DM1) is very poor. Annual 24-hour holter ECG monitoring is recommended but its relevance is debated. Main objective was to determine whether holter ECG parameters could predict global death in DM1 patients and secondarily to assess whether they could predict cardiovascular events and sudden cardiac death, to compare DM1 patients and healthy controls, and to assess their evolution in DM1 over a 5-year period. METHODS: This retrospective study included genetically confirmed DM1...

The presence of left bundle branch block (LBBB) is an important predictor of benefit from cardiac resynchronization therapy (CRT). New "strict" electrocardiographic (ECG) criteria for LBBB have been shown to better predict benefit from CRT. The "strict" LBBB criteria include: QRS duration ≥140 ms (men) or ≥130 ms (women), QS- or rS-configurations of the QRS complex in leads V1 and V2, and mid-QRS notching or slurring in ≥2 of leads V1, V2, V5, V6, I and aVL. The "strict" LBBB criteria are not regularly used and most hospital automated ECG systems and physicians still use more conventional LBBB criteria...

BACKGROUND: Cardiovascular diseases (CVD) are the leading cause of morbidity and mortality worldwide. Early diagnosis is of pivotal importance for patients with cardiac arrhythmias and ischemia to minimize the consequences like strokes and myocardial infarctions. The chance of capturing signals of arrhythmias or ischemia is substantially high when a 12-lead electrocardiogram (ECG) can be recorded at the moment when a patient experiences the symptoms. However, until now, available diagnostic systems (Holter monitors and other wearable ECG sensors) have not enabled patients to record a reliable 12-lead ECG at home...
