Background High-intensity physical activity has traditionally been discouraged in patients with hypertrophic cardiomyopathy due to concerns about triggering sudden cardiac death. However, current guidelines adopt a more liberal stance, and evidence on risk factors for exercise-related sudden cardiac death remains limited.

” While an awe-inspiring anecdote, our knowledge of human limits, physiology, and the sheer number of participants in endurance sports is enough evidence to conclude that running a marathon won’t kill you. Physiologically Speaking is a reader-supported publication. Many, but not all, are cardiac-related issues (i.e.,

BACKGROUND:Commotio cordis, sudden cardiac death (SCD) caused by relatively innocent impact to the chest, is one of the leading causes of SCD in sports. A physiological commotio cordis model was utilized to assess variables that predicted for SCD.

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. AV block is the first manifestation of CS in more than 30% of patients.

We wish, our understanding about cardiac contractile physiology is deep and nearly complete. In myocardial pathology, the genesis and sustainability of ventricular arrhythmia are intricately related to the degree of LV dysfunction of any cause. Reference 1. N Engl J Med. 2005 Jan 20;352(3):225-37.

Background Atrial fibrillation, the most sustained common arrhythmia, is increasing in incidence and prevalence in the United States and globally. Stages of AF The previous classification of AF was based on arrhythmia duration which placed more emphasis on therapeutic interventions once AF was diagnosed. million.
