Supraventricular arrhythmias:

Supraventricular tachycardia (SVT), additionally called paroxysmal supraventricular tachycardia, is characterized as an unusually quick heartbeat. It's a wide term that incorporates numerous types of heart musicality issues (heart arrhythmias) that begin over the ventricles (supraventricular) in the atrial hub. A normal heart rate is 60 to 100 beats per minute. tachycardia is the condition where the heartbeat exceeds abnormally up to more than 100 beats per second. This occurs when the electrical impulses that coordinate your heartbeats don't work properly.

Symptoms

Signs and manifestations of supraventricular tachycardia may include:

• A rippling in your chest
• Fast heartbeat (palpitations)
• Windedness
• wooziness
• Perspiring
• A beating sensation in the neck
• Blacking out (syncope) or close swooning

In babies and small kids, signs and indications might be hard to recognize. Perspiring, helpless taking care of, fair skin and newborn children with a heartbeat rate more prominent than 200 thumps for every moment may have supraventricular tachycardia.

Supraventricular arrhythmias:

Supraventricular arrhythmias refer to a group of heart rhythm disorders that originate above the ventricles in the atria of the heart. These types of arrhythmias are characterized by rapid and irregular heartbeats, which can cause symptoms ranging from mild palpitations to more serious issues like shortness of breath, chest pain, and fainting. 

Causes

The causes of supraventricular arrhythmias include:

• Abnormalities in the heart's electrical system
• High levels of stress or anxiety
• Heart disease or heart attack
• Use of stimulant medications or drugs
• Alcohol or caffeine consumption
• Chronic medical conditions, such as lung disease or hyperthyroidism

Symptoms

Signs and manifestations of supraventricular arrhythmias may include:

• Rapid or irregular heartbeat
• Lightheadedness or fainting
• Chest pain or discomfort
• Shortness of breath
• Dizziness or weakness

Diagnosis

The diagnosis of supraventricular arrhythmias typically involves a combination of a physical exam, medical history, and various tests to evaluate heart function and identify any underlying causes.

• Physical exam and medical history
• Electrocardiogram (ECG) to measure the heart's electrical activity
• Holter monitor to record heart activity over a 24-hour period
• Echocardiogram to visualize heart structure and function
• Blood tests to check for underlying conditions
