Abstract

Slow ventricular tachycardia (VT) in patients with devices such as an implantable cardioverter - defibrillator (ICD) is more common than in the rest of the population. The incidence in elderly patients with an ICD remains largely unknown. In younger patients, slow VT is generally asymptomatic or associated with limited clinical relevance. It may be efficiently and safely terminated by anti-tachycardia pacing. We present a case of slow VT in a 91-year-old man with ICD with type 1 acute respiratory failure and drowsiness. Very elderly patients who have poor cardiac reserve and minor deterioration in cardiac function can face serious consequences such as ventricular fibrillation, cardiac arrest, and sudden cardiac death. The persistent ventricular rhythm may have a deleterious effect on their haemodynamic status, with potential aggravation of symptoms of heart failure and further impairment of ventricular function.

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.
