Final answer:
Paroxysmal Atrial Tachycardia (PAT) or Paroxysmal Supraventricular Tachycardia (PSVT) is a type of heart arrhythmia with sudden episodes of rapid heart rate at rest. It is characterized by symptoms like palpitations and dizziness and diagnosed with tools like an ECG. Treatment varies based on the cause but can include medications or surgical interventions.
Step-by-step explanation:
Paroxysmal Atrial Tachycardia (PAT) or Paroxysmal Supraventricular Tachycardia (PSVT)
Paroxysmal Atrial Tachycardia (PAT), also known as Paroxysmal Supraventricular Tachycardia (PSVT), is a condition characterized by sudden episodes of a rapid heart rate that begins and ends abruptly. The key features of this arrhythmia include a heart rate that is significantly faster than normal (usually above 100 beats per minute) when at rest. Symptoms may not always be present, but when they are, they can include palpitations, dizziness, shortness of breath, chest pain, or fainting (syncope). PSVT falls under one of the four main groups of arrhythmia, specifically categorized as a supraventricular tachycardia. This rapid heart rate originates from the atria or above the ventricles.
To diagnose and evaluate PSVT, healthcare professionals utilize diagnostic tests such as an electrocardiogram (ECG) and Holter monitor to observe the heart's electrical activity. Treatment options depend on the underlying cause and can range from medications to medical procedures like ablation surgery or the implantation of a cardioverter defibrillator.
Heart arrhythmias are potentially serious conditions as they can lead to additional complications such as stroke or heart failure. Nevertheless, with proper diagnosis and treatment, many patients are able to manage their PSVT effectively.
