A weakening or cessation of the contractile power of the heart.
The complete absence of ventricular contractions in the heart. See also cardiac standstill.
absence of systole; failure of the ventricles of the heart to contract (usually caused by ventricular fibrillation) with consequent absence of the heart beat leading to oxygen lack and eventually to death
An absence of electromechanical activity within the heart. Appears on the electrocardiogram (ECG, EKG) monitor as a straight or 'flat line'. This rhythm cannot be shocked by a defibrillator.
(Cardiac Arrest, Ventricular Standstill): The absence of a heartbeat.
Cardiac standstill or arrest; absence of a heartbeat .
Absence of ventricular contractions of the heart.
A period during which the heart does not contract. recorded on a tracing as a straight line.
Period in which the heart does not contract; standstill.
Absence of electrical activity in the heart.
Complete absence of heart electrical and pumping activity
Asystole is when the heart does not beat.
In medicine, asystole is a state of no cardiac electrical activity, hence no contractions of the myocardium and no cardiac output or blood flow. Asystole is one of the conditions required for a medical practitioner to certify death.
