Sinus node dysfunction ( SND ), also known as sick sinus syndrome ( SSS ), is a group of abnormal heart rhythms ( arrhythmias) usually caused by a malfunction of the sinus node, the heart's primary pacemaker. [1] [2] Tachycardia-bradycardia syndrome is a variant of sick sinus syndrome in which the arrhythmia alternates between fast and slow ...
Transcutaneous pacing ( TCP ), also called external pacing, is a temporary means of pacing a patient's heart during a medical emergency. It should not be confused with defibrillation (used in more serious cases, in ventricular fibrillation and other shockable rhythms) using a manual or automatic defibrillator, though some newer defibrillators ...
Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [ 1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block. Resting heart rates of less than 50 BPM are often ...
Inappropriate sinus tachycardia (IST) is defined as sinus tachycardia that is not caused by identifiable medical ailments, a physiological reaction, or pharmaceuticals (a diagnosis of exclusion) and is accompanied by symptoms, frequently invalidating and affecting quality of life. [ 2] IST symptoms include palpitations, chest discomfort ...
Acute coronary syndrome ( ACS) is a syndrome (a set of signs and symptoms) due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. [ 1] The most common symptom is centrally located pressure-like chest pain, often radiating to the left shoulder [ 2] or angle of the jaw, and ...
Sinus bradycardia. ECG of Sinus bradycardia with a heart rate of 43 bpm. Sinus bradycardia is a sinus rhythm with a reduced rate of electrical discharge from the sinoatrial node, resulting in a bradycardia, a heart rate that is lower than the normal range (60–100 beats per minute for adult humans). [ 1][ 2]
antiarrythmic agents, diuretics, catheter ablation, pacemaker [ 1] Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure. [ 1][ 5] People with TIC may have symptoms ...
Transvenous cardiac pacing ( TVP ), [1] also called endocardial pacing, is a potentially life-saving intervention used primarily to correct profound bradycardia. It can be used to treat symptomatic bradycardias that do not respond to transcutaneous pacing or to drug therapy. Transvenous pacing is achieved by threading a pacing electrode through ...
