Tachycardia is a heart rate that exceeds 100 beats per minute in an adult, though is of greater concern when it exceeds 150.[1][3] Symptoms may vary from none to severe.[1] These may include palpitations, light headedness, shortness of breath, chest pain, or syncope.[1]
Types include sinus tachycardia, paroxysmal supraventricular tachycardia, atrial fibrillation, atrial flutter, extra beats such as atrial premature beats and ventricular premature beats, ventricular tachycardia, and ventricular fibrillation.[2] Underlying risk factors include low oxygen, fever, heart disease, stimulants, and electrolyte abnormalities.[1][3] Diagnosis is by electrocardiogram (ECG).[1] They can be divided into narrow complex and wide complex and than further divided into regular and irregular.[1]
Treatment depends on the type of tachycardia.[1] An underlying cause may need to be addressed, if present.[3] If a person is unstable due to the tachycardia, synchronized cardioversion is generally recommended, though in certain cases adenosine may be used.[3] If the QRS complex is narrow and the person is stable vagal maneuvers, adenosine, beta blockers, or calcium channel blockers may be used.[3] Tachycardia is common.[4]
