Hypertrophic cardiomyopathy and atrial fibrillation: the Cardiomyopathy/Myocarditis Registry of the EURObservational Research Programme of the European Society of Cardiology

Open Heart

Background Hypertrophic cardiomyopathy (HCM) is commonly associated with atrial fibrillation (AF), but its impact on outcomes in real-world practice is uncertain. The aim of the study was to evaluate the clinical profile and prognosis of patients with HCM and AF. Methods Overall, 1739 adult patients with HCM (40.9%

Medics found him in ventricular fibrillation. He was defibrillated, but they also noticed that he was being internally defibrillated and then found that he had an implantable ICD. He was unidentified and there were no records available After 7 shocks, he was successfully defibrillated and brought to the ED.

A multicenter analysis of implantable monitoring device-based diagnosis of supraventricular arrhythmia post patent foramen ovale closure: the OCCL-ILR study

Frontiers in Cardiovascular Medicine

Primary endpoint was the incidence of patients with new onset supraventricular arrhythmia (AF, atrial flutter or any supraventricular tachycardia) lasting >30s, post PFO closure.ResultsA total of 59 patients met the inclusion criteria.

Incidental Arrhythmias During Atrial Fibrillation Screening With Repeat 7?Day Holter ECGs in a Hospital?Based Patient Population

Journal of the American Heart Association

BackgroundScreening for atrial fibrillation (AF) may reveal incidental arrhythmias of relevance. Among these were sinus node dysfunction in 14 patients (1.8%), AVB in 41 (5.2%), supraventricular tachycardia in 42 (5.3%), and ventricular tachycardia in 2 (0.3%).

Abstract 4143264: A Case of Spike-on-T Phenomenon and Polymorphic Ventricular Tachycardia

Circulation

This can initiate ventricular arrhythmias like polymorphic ventricular tachycardia (PMVT). She was externally defibrillated with 200J and received magnesium and an IV amiodarone bolus. She was successfully defibrillated with 360J. Telemetry showed Spike-on-T phenomenon which initiated PMVT.

Does this T wave pattern mean anything?

She was successfully revived after several rounds of ACLS including defibrillation and amiodarone. An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). In particular — QRS alternans during narrow SVT rhythms has been associated with reentry tachycardias.

What is this rhythm? Back to basics.

Dr. Smith's ECG Blog

Artifact can obscure the rhythm or cause misdiagnosis of rhythms such as atrial fibrillation, ventricular tachycardia, and ventricular fibrillation. As worrisome as the initial recording in leads I and II look — a glance at lead III should immediately reassure us that defibrillation is not needed!
