The management of tachycardia depends on its type (wide complex versus narrow complex), whether or not the person is stable or unstable, and whether the instability is due to the tachycardia. [10] Unstable means that either important organ functions are affected or cardiac arrest is about to occur. [ 10 ]
Paroxysmal supraventricular tachycardia (PSVT) is a type of supraventricular tachycardia, named for its intermittent episodes of abrupt onset and termination. [3] [6] Often people have no symptoms. [1] Otherwise symptoms may include palpitations, feeling lightheaded, sweating, shortness of breath, and chest pain. [2] The cause is not known. [3]
Junctional ectopic tachycardia (JET) is a rare tachycardia caused by increased automaticity of the AV node itself initiating frequent heartbeats. On the ECG, junctional tachycardia often presents with abnormal morphology P-waves that may fall anywhere in relation to a regular, narrow QRS complex. It is often due to drug toxicity. [22]
[1] [5] [6] Treatment of TIC can involve treating the heart failure as well as the tachycardia or arrhythmia. [1] TIC has a good prognosis with treatment, with most people recovering some to all of their heart function. [1] The number of cases that occur is unclear. [5] TIC has been reported in all age groups. [6]
Amiodarone may be used in cases of ventricular fibrillation, ventricular tachycardia, and wide complex tachycardia. [109] Lidocaine is a Class IB anti-arrhythmic, also used to manage acute arrhythmias. [110] Anti-arrhythmic medications may be used after an unsuccessful defibrillation attempt.
Chest pain with features characteristic of cardiac origin (angina) can also be precipitated by profound anemia, brady-or tachycardia (excessively slow or rapid heart rate), low or high blood pressure, severe aortic valve stenosis (narrowing of the valve at the beginning of the aorta), pulmonary artery hypertension and a number of other conditions.
Pediatric advanced life support (PALS) is a course offered by the American Heart Association (AHA) for health care providers who take care of children and infants in the emergency room, critical care and intensive care units in the hospital, and out of hospital (emergency medical services (EMS)). The course teaches healthcare providers how to ...
The electrocardiogram (ECG) would appear as a narrow-complex SVT. Between episodes of tachycardia the affected person is likely to be asymptomatic; however, the ECG would demonstrate the classic delta wave in Wolff–Parkinson–White syndrome. [2]
