Factors associated with high-intensity physical activity and sudden cardiac death in hypertrophic cardiomyopathy

Heart BMJ

FEBRUARY 26, 2025

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.

Effect of SGLT-2 inhibitors on arrhythmia events: insight from an updated secondary analysis of?>?80,000 patients (the SGLT2i—Arrhythmias and Sudden Cardiac Death)

Cardiovascular Diabetology

FEBRUARY 23, 2024

Objective We aimed to assess the effect of SGLT2i on arrhythmias by conducting a meta-analysis using data from randomized controlled trials(RCTs). Background Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have shown cardioprotective effects via multiple mechanisms that may also contribute to decrease arrhythmias risk.

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.

There are a number of things to look for in an ECG that can hint at arrhythmia as the cause of an apparent seizure.
