An essential organ, the heart pumps blood throughout the body to supply muscles and organs with nutrition and oxygen while expelling waste materials and carbon dioxide. It serves as the primary organ of the circulatory system, a system of blood vessels that transports blood throughout the body.

What Are the Functions of the Heart?

Blood is pumped with oxygen to other bodily parts. they deliver essential chemicals, such as hormones, to various body parts. receiving blood that has been deoxygenated, removing waste products from metabolism, and pumping them to the lungs where they are oxygenated. They keep their blood pressure constant ^[1].

What Happens If the Heart Has an Irregular Beat?

An arrhythmia is an irregular heartbeat. Other symptoms, such as weakness or exhaustion, lightheadedness, fainting, shortness of breath, perspiration, and pressure or pain in the chest, can appear as a result of persistent arrhythmias. Unusual heartbeats can occasionally be harmless and go away on their own.

However, they can become dangerous if they keep happening. An irregular heartbeat impairs the heart's ability to pump oxygen-rich blood effectively, thereby endangering the heart and other organs. For instance, an excessively rapid heartbeat can cause the ventricles to quiver, which can result in sudden cardiac arrest—an unexpected loss of heart function^[2].

Different types of Arrhythmia.

• Atrial fibrillation
• Atrial flutter
• Sinus tachycardia
• Bradycardia
• Ventricular fibrillation 
• Ventricular tachycardia^[2]

What is A Regular Heart Rhythm?

A regular heartbeat falls between 60 and 100 beats per minute; this is referred to as a normal sinus rhythm. Your heart beats rhythmically, pumping enough oxygen-rich blood at this rhythm. If your heart beats between 60 and 100 times per minute, it is healthy^[2].

When To See Your Physician?

If you experience heart palpitations, weakness, fatigue, trouble catching your breath, dizziness, fainting, and chest tightness, seek help immediately. Trying to push through an arrhythmia could lead to more dangerous complications^[2].
