The condition, often referred to as paroxysmal supraventricular tachycardia, is characterized by sudden episodes of rapid heart rate above the ventricles. Here is a brief overview of its symptoms, diagnosis, treatment, and prevention.
The cause of PSVT is often abnormal electrical pathways in the heart, which cause rapid and irregular heartbeats.
In susceptible individuals, stimulants such as caffeine, nicotine, or recreational drugs can trigger PSVT episodes.
The onset of PSVT episodes is sometimes precipitated by emotional distress or anxiety.
There is a possibility that PSVT is associated with underlying heart conditions such as atrial fibrillation, atrial flutter, or Wolff-Parkinson-White syndrome.
Heart Rate Intermittent: When PSVT episodes occur, the heart rate suddenly rises to over 100 beats per minute, resulting in palpitations or chest pounding.
Insufficiency of Breath: Rapid heart rate may cause insufficiency of breath or difficulty breathing.
It is possible for individuals to experience chest discomfort or pain during episodes of PSVT.
It is possible to experience dizziness or fainting during PSVT episodes because of reduced blood flow to the brain.
A PSVT diagnosis is typically confirmed by an electrocardiogram (ECG), which records the electrical activity of the heart during an episode.
In some cases, Holter monitors can be used to record heart electrical activity over a longer period of time to capture episodes of intermittent PSVT.
ECG: An ECG can be performed to identify specific locations in the heart where abnormal electrical pathways exist and to guide treatment decisions.
The vagus nerve can sometimes be stimulated by certain methods, such as the Valsalva maneuver or carotid sinus massage, which can sometimes assist in terminating PSVT episodes.
It is possible to control heart rate and rhythm with antiarrhythmic medication during PSVT episodes or avoid future episodes with these medications.
Electrical cardioversion may be performed if PSVT episodes are prolonged or symptomatic, in order to restore normal heart rhythm.
The catheter ablation procedure may be recommended to individuals with frequent or severe PSVT episodes as a means of destroying abnormal electrical pathways within the heart.
The most effective way to prevent PSVT episodes is to identify and avoid triggers such as caffeine, nicotine, stress, and other substances that cause PSVT.
In order to prevent recurrent PSVT episodes, it is important to take prescribed medications regularly as directed by a healthcare provider.
Practicing stress-reduction techniques such as meditation or deep breathing exercises may help to prevent PSVT episodes in susceptible individuals.
Keeping an eye on the condition and adjusting the treatment as necessary is crucial for regular follow-up appointments with a cardiologist.
