FAQ

The four signs your heart may be quietly failing are syncope, dizziness, cardiac arrest, and seizure-like activity—often due to ventricular standstill.

A heart pause is concerning if it lasts more than a few seconds, typically over 3 seconds, as it may indicate dangerous arrhythmias like ventricular standstill.

The four subtle signs may include syncope, dizziness, seizure-like activity, and unexpected cardiac arrest—all of which may indicate ventricular standstill.

A heart pause becomes concerning when it lasts more than a few seconds, as this can result in loss of consciousness or absent pulse due to lack of ventricular activity.

Four potential signs of quiet heart failure include syncope (fainting), dizziness, seizure-like activity, and cardiac arrest, often due to ventricular standstill.

A heart pause lasting more than a few seconds is concerning and may lead to loss of consciousness or cardiac arrest.

Ventricular standstill is characterized by ongoing atrial activity (P waves) without ventricular response, while asystole reflects complete electrical silence of the heart.

On ECG, ventricular standstill presents as regular P waves without accompanying QRS complexes, reflecting absence of ventricular activity.

Yes, ventricular standstill can be lethal due to the abrupt cessation of cardiac output, leading to syncope, seizures, or cardiac arrest if not promptly treated.

Ventricular standstill is a rare, potentially fatal arrhythmia where the ventricles cease all electrical activity, leading to loss of cardiac output and often unconsciousness.
