Prognosis And Treatment Of Abnormal Heartbeats



Prognosis and​ Treatment of​ Abnormal Heartbeats
Most arrhythmias (abnormal heartbeats) neither cause symptoms nor interfere with the​ heart's ability to​ pump blood .​
Thus, they usually pose little or​ no risk .​
They can cause considerable anxiety if​ a​ person becomes aware of​ them .​
There are some arrhythmias, harmless in​ themselves that can lead to​ more serious arrhythmias.
Any arrhythmia that impairs the​ heart's ability to​ pump blood adequately is​ serious .​
How serious, depends in​ part on where the​ arrhythmia originates .​
is​ it​ in​ the​ heart's normal pacemaker, in​ the​ atria, or​ in​ the​ ventricles? Generally, arrhythmias which originate in​ the​ ventricles are more serious than those that originate in​ the​ atria .​
These are more serious than those that originate in​ the​ pacemaker .​
However, there are many exceptions.
For people who have a​ harmless, yet worrisome arrhythmia, reassurance that the​ arrhythmia is​ harmless may be treatment enough .​
Sometimes arrhythmias occur less often or​ even stop, when doctors change a​ person's drugs or​ adjust the​ dosages .​
Avoiding alcohol, caffeine, smoking, or​ strenuous exercise can also help.
Antiarrhythmic drugs are useful for​ suppressing fast arrhythmias that cause intolerable symptoms or​ pose a​ risk .​
No single drug cures all arrhythmias in​ people .​
Sometimes several drugs must be tried until the​ response is​ satisfactory .​
Sometimes antiarrhythmic drugs can worsen or​ even cause arrhythmias; this effect is​ called proarrhythmia .​
Antiarrhythmic drugs can also produce other side effects.
Artificial pacemakers are electronic devices that act in​ place of​ the​ heart's own pacemaker .​
These devices are implanted surgically under the​ skin, usually below the​ left or​ right collarbone .​
They are connected to​ the​ heart by wires running inside a​ vein .​
New circuitry has almost completely eliminated the​ risk of​ interference from automobile distributors, radar, microwaves, and​ airport security detectors.
Any abnormality within the​ chest is​ wise to​ get checked out by your family doctor.
