Definition of Cardiac Arrhythmia
It is a plight in which normal heart-beat replace by off-track heart-beat
Clinical problems encountered are
Frequently reported problem are
The most common symptom is palpitation and unawareness of an abnormal Cardiac-beats.
Some patients with clearly documented arrhythmia have no palpitation in some exceptional cases!
Arrhythmia starts suddenly and thus, if the patient clearly describe palpitation of sudden onset like, clicking a switch this is a useful pointer to an earlier than heightened awareness of sinus-tachycardia, which has sudden onset!
Graphical symptoms that arise due to reduce cardiac output include, reduce exercise capacity and fatigue!
Can lead to tachycardia (elevated in heart-beat) even in the absence of heart’s artery disease!
elevated metabolic-rate of heart muscle and elevated demand for blood flow a.k.a myocardial perfusion dominantly during diastole, and during tachycardia proportionality less time is spent in diastole and thus, heart’s demand for blood can exceed supply resulting in an angina!
Sudden drop in cardiac output
Can leads towards bradycardia or tachycardia causing episode of dizziness, loss of consciousness or in extreme cases sudden death from heart arrest is also reported!
Development of clot called as thrombus or embolism to any part of body except heart is known as peripheral thrombosis or peripheral embolism is the characteristic symptoms without causing ischemic attack or stroke, and can aggravate cardiac-failure!
The heamodynamic effect of arrhythmia precipitate heart failure or aggregate existing cardiac-failure to prolonged tachycardia of any type, may also leads to cardiomyopathy!
