Heart Arrhythmia: Is It Dangerous?

Saturday, 08 Mar 2014 10:08 PM

Heart arrhythmia is a condition that is caused when heartbeats are irregular. For a normal human heart, the average number of heartbeats per minute is between 60 and 100. The heartbeat count and its rhythm is controlled by the heart’s pacemaker and electrical impulses that are created in the heart’s chambers and valves as blood passes through them.
In the case of heart arrhythmia, the electrical impulses are impaired suddenly for a short duration, leading to fibrillation (rapid heartbeats), tachycardia, and palpitations.
 
Are Heart Arrhythmias Dangerous?

Though all heart arrhythmias are not dangerous, many of them could give rise to other cardiac problems, sudden cardiac arrest, heart problems, congestive heart failure, and stroke to name a few.
 
Atrial fibrillation affects more people and causes a quick quiver and about 200 heartbeats a minute. Though it is not life-threatening, atrial fibrillation can lead to fatigue, heart failure, and stroke in the long run.
 
Ventricular fibrillation causes sudden cardiac arrest and is the most dangerous of all heart arrhythmia. It is the reason for 50 percent of all cardiac deaths.
 
Tachycardia is another condition which causes rapid heartbeat, palpitations, and shortness of breath. Ventricular tachycardia is considered life-threatening and requires electrical jolt and treatments; it does not stop on its own.
 
Heart Arrhythmia and Catheter Ablation

Fibrillation and heart arrhythmia can be treated using anti-arrhythmia medications. In some cases, a pacemaker (device implanted into the heart to stimulate rhythmic electrical impulses) may be implanted into the heart in order to correct heartbeat and palpitations by addressing the underlying issue of improper electrical impulses in the heart. Sometimes, a defibrillator is used to slow down heartbeat and prevent atrial and ventricular fibrillation that may be caused from time to time and it is clearly detected while monitoring a person’s heartbeat.
 
However, catheter ablation is a modern technique that helps permanently resolve the issue of heart arrhythmia before it causes major catastrophe. Ablation is a technique in which a catheter is guided in the artery through the arm, thigh, or neck. During ablation, the catheter, which receives electrical signals from an external device, is sent to reach the heart from inside the blood vessels. Once the catheter reaches the area that is prone to heart arrhythmia and fibrillation, heat is released from the catheter that causes ablation and resultant destruction of malfunctioning heart cells, which easily cause fibrillation, palpitation, tachycardia, or other heart arrhythmia leading to irregular heartbeats. Ablation is practiced worldwide and is a safe method to prevent heart arrhythmia, fibrillation, palpitations, and irregular heartbeat.

Though all heart arrhythmia, fibrillation, and palpitations do not necessarily cause serious heart problems, certain severe heart arrhythmia and their repetitive occurrence can lead to the development of congestive heart failure, stroke, cardiac arrest, and other complications.
