Progressive decline across periods in mortality rates among patients with implantable cardioverter-defibrillator (ICD). Abstract Introduction Despite advancements in implantable cardioverter-defibrillator (ICD) technology, sudden cardiac death (SCD) remains a persistent public health concern.

Most patients with VT and structural heart disease preparing for ablation either have or are about to receive an implantable cardioverter defibrillator (ICD) shortly after the procedure to prevent sudden cardiac death from recurrent ventricular arrhythmias (VA).

Cardiovascular mortality, driven by sudden cardiac death, is the main reason for dying while waiting for heart transplantation (HTx). Methods CASTLE-VT is a randomized evaluation of prophylactic ablative treatment of arrhythmogenic ventricular scar in patients referred for HTx evaluation and diagnosed with ICM.

After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation. The patient was diagnosed with stress cardiomyopathy. Widespread T wave inversions and prolongation of the QT interval is not uncommon in Takotsubo cardiomyopathy.

She was given CRT-D (Cardiac Resynchronization Therapy-Defibrillator). The granulomatous inflammation affects the heart, causing an infiltrative cardiomyopathy The most common manifestations of cardiac sarcoidosis are atrioventricular (AV) block and ventricular tachyarrhythmias (VT). VT is the second most common presenting arrhythmia.

In myocardial pathology, the genesis and sustainability of ventricular arrhythmia are intricately related to the degree of LV dysfunction of any cause. Tackling SCD was in God’s domain, until the brilliance of Dr. Michel Mirowski shrunk the defibrillator and implanted it under the chest in 1980. (Dr. N Engl J Med. N Engl J Med.

ABSTRACT Cardiomyopathies are a significant contributor to cardiovascular morbidity and mortality, mainly due to the development of heart failure and increased risk of sudden cardiac death (SCD). Despite improvement in survival with contemporary treatment, SCD remains an important cause of mortality in cardiomyopathies.
