Potentially fatal b/c the heart is beating so rapidly that it is unable to adequately pump blood through the body Which term means rapid random and ineffective contractions of the heart?Ventricular fibrillation refers to rapid, irregular, and weak contractions of the ventricles, resulting in no effective blood flow out of the heart (cardiac arrest).
What is the term for rapid irregular rhythms of the ventricle quizlet?Ventricular Fibrillation. the rapid, irregular, and useless contractions of the ventricles.
Which condition is the rapid irregular and useless contractions quivering of the ventricles that may result in sudden cardiac death?Ventricular fibrillation is a condition in which the heart's electrical activity becomes disordered. When this happens, the heart's ventricles, the lower chambers that pump blood, contract in a rapid, unsynchronized way. The ventricles "flutter" rather than beat, causing the heart to pump little or no blood.
What term describes rapid ineffectual contractions of the ventricles?Introduction. Pulseless ventricular tachycardia is a life-threatening cardiac arrhythmia in which coordinated ventricular contractions are replaced by very rapid but ineffective contractions, leading to insufficient organ perfusion and heart failure. Pulseless ventricular tachycardia is a medical emergency.
