Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).
Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans).
Bigeminy is contrasted with couplets, which are paired abnormal beats. Groups of three abnormal beats are called triplets and are considered a brief run of non-sustained ventricular tachycardia (NSVT), and if the grouping lasts for more than 30 seconds, it is ventricular tachycardia (VT). [2]
Tachycardia describes an abnormally rapid heart rate. By stringing these words together, you can see that POTS is a description of symptoms that commonly occur together, otherwise known as a ...
A rapid, regular heartbeat is usually due to paroxysmal SVT or ventricular tachycardia. [1] A rapid, irregular rhythm might be due to atrial fibrillation, atrial flutter, or tachycardia with a variable block. [1] Supraventricular and ventricular tachycardias often cause sudden palpitations. They start and stop quickly.

Symptoms of right atrial enlargement include palpitations, dyspnea, paroxysmal tachycardia, general malaise, shortness of breath, syncope, chest pain, fatigue, cyanosis, loss of appetite, tachycardia, fever, and cough. Many patients with right atrial enlargement are asymptomatic.
This person was eventually diagnosed with tachycardia-induced cardiomyopathy. [7] There are no specific diagnostic criteria for TIC, and it can be difficult to diagnose for a number of reasons. First, in patients presenting with both tachycardia and cardiomyopathy, it can be difficult to distinguish which is the causative agent. [5]
