Abstract

This article reports the case of a 76-year-old patient with multiple implantable cardioverter defibrillator (ICD) interventions of the single chamber ICD. On admission the 12-lead electrocardiogram (ECG) documented a wide QRS complex tachycardia without clearly identifiable P waves. The patient had previously had two ventricular tachycardia (VT) ablations due to VT storms. The resting ECG revealed a sinus rhythm with a wide QRS complex. During the electrophysiological investigation typical atrial flutter could be detected and an ablation of the cavotricuspid isthmus was performed. During the follow-up period, the patient has been free from tachycardia. The case described emphasizes that a differentiation between supraventricular tachycardia (SVT) and VT based on a stored ECG without an atrial channel can be challenging.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.
