Causes of heart arrhythmia

Heart arrhythmia is the scenario where the heart beats at an irregular pace or pattern, sometimes more than a 200 beats per minute or sometimes as low as 50-60 per minutes.

The causes of arrhythmia can be divided into two categories. Primary rhythm disturbances, which not associated with any underlying heart disease and secondary rhythm disturbances, arise from existing heart conditions.

Primary rhythm disturbances such as:
*Smoking
*Excessive use of alcohol or caffeine
*Drug abuse
*Some prescription medications and herbal remedies

While secondary rhythm disturbances including:
*Heart defects at birth
*Electrolyte imbalances in your blood (such as sodium or potassium)
*Changes in your heart muscle
*Injury from a heart attack
*Stress
*Healing process after heart surgery
*Irregular heart rhythms can also occur in "normal, healthy" hearts.

Risk factors include: coronary artery disease; high blood pressure, high blood cholesterol levels, unhealthy lipid or triglyceride blood levels; atherosclerosis, diabetes, thyroid-gland orders; and damaged heart valves.

Symptoms of heart arrhythmia

Arrhythmia can lead to cardiopulmonary arrest and death; otherwise, the symptom of arrhythmia can be subtle and intermittent.

It is the result of a disturbance that alters the transmission of electrical impulses within the heart affecting the normal rhythm or rate of the heartbeat.

The symptoms are primarily due to the hemodynamic effects to the cardiac rhythm disturbance. Noticeable arrhythmia symptoms may include:
*A fluttering in your chest
*A racing heartbeat (tachycardia)
*A slow heartbeat (bradycardia)
*Chest pain
*Shortness of breath
*Peripheral vascular embolization Dyspnea
*Acute neurologic deficits
*Lightheadedness or dizziness
*Sweating Isolated or recurrent loss of consciousness (syncope) or near fainting
