Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat. Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat , or normal heartbeat.
Premature ventricular contraction in an ECG (arrows) of a dog, caused by dilated cardiomyopathy. Premature ventricular contractions occur in healthy persons of any age, but are more prevalent in the elderly and in men. [3] In a very significant proportion of people they occur spontaneously with no known cause. [citation needed]
About 80% of sudden cardiac death is the result of ventricular arrhythmias. [12] Arrhythmias may occur at any age but are more common among older people. [4] Arrhythmias may also occur in children; however, the normal range for the heart rate varies with age. [3]
Left ventricular hypertrophy is a leading cause of sudden cardiac deaths in the adult population. [ 39 ] [ 30 ] This is most commonly the result of longstanding high blood pressure , or hypertension, which has led to maladaptive overgrowth of muscular tissue of the left ventricle , the heart's main pumping chamber. [ 40 ]
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
Statins are generally recommended for adults between the ages of 40 and 75 who have heart disease risk factors. Despite having higher risks for cardiovascular disease, fewer older adults use statins.
Dave Chappelle will appear on 'Saturday Night Live's 50th anniversary special despite his transphobic statements and "jokes." Why does 'SNL' keep giving him a platform?
QRS duration greater than 180 milliseconds, older age at repair (greater than three years), significant pulmonary valve or tricuspid valve regurgitation, history of syncope, multifocal premature ventricular contractions, and ventricular tachycardia are some of the factors associated with sudden death after 30 years of procedure.
