People with TIC most often present with symptoms of congestive heart failure and/or symptoms related to their irregular heart rhythm. [1] Symptoms of congestive heart failure can include shortness of breath, ankle swelling, fatigue, and weight gain. [2] Symptoms of an irregular heart rhythm can include palpitations and chest discomfort. [2]
Beta blockers - reduces contractility and automaticity of the heart which reduces irregular rhythms but also lowers blood pressure when symptoms occur, and further reduces perfusion ex: Carvedilol, this will control abnormal heart rhythms, but can precipitate Prinzmetal angina and heart block.
Pacemakers are often used for slow heart rates. [6] Those with an irregular heartbeat are often treated with blood thinners to reduce the risk of complications. [6] Those who have severe symptoms from an arrhythmia or are medically unstable may receive urgent treatment with a controlled electric shock in the form of cardioversion or ...
Over time, however, there may be decompensation and patients can develop volume overload (congestive heart failure). Symptoms of entry into a decompensated phase may include fatigue, shortness of breath particularly on exertion, and leg swelling. Also, there may be development of an irregular heart rhythm known as atrial fibrillation. [6]
A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia. During an episode of SVT, the heart beats about 150 to 220 times per minute. [9] Specific treatment depends on the type of SVT [5] and can include medications, medical procedures, or surgery. [5]
Those affected by arrhythmogenic cardiomyopathy may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. [6] If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in arrhythmogenic cardiomyopathy may take the form of palpitations, or blackouts. [7]
Cardiac symptoms of heart failure include chest pain/pressure and palpitations.Common noncardiac signs and symptoms of heart failure include loss of appetite, nausea, weight loss, bloating, fatigue, weakness, low urine output, waking up at night to urinate, and cerebral symptoms of varying severity, ranging from anxiety to memory impairment and confusion.
An automatic tachycardia is a cardiac arrhythmia which involves an area of the heart generating an abnormally fast rhythm, sometimes also called enhanced automaticity.These tachycardias, or fast heart rhythms, differ from reentrant tachycardias (AVRT and AVNRT) in which there is an abnormal electrical pathway which gives rise to the pathology.
