Electrical block?: This answer applies to electrical block which is different than an arterial block. There are many different types of "heart block" with vast ranging significance. Because of that the symptoms are widely varied. While some result in no symptoms others may result in fainting, fatigue or difficulty breathing with exertion. An ECG should help to differentiate the specific type of heart block.

Is a heart block a chronic disorder in the heart?

Arrhythmia: Heart block leading to a slowed heart rate can be acute, occurring secondary to external circumstances like increased vagal stimulation, low oxygen levels, or threatened coronary circulation. It can also be chronic occurring as a result of conduction system disease in patients with sleep apnea, myocardial scarring, aging, or infiltrative deposits.

Is a first degree av heart block condition treatable?

Dr. Michael Zevitz

No: Treatment of first degree av block is not required except in very severe cases with a very long delay in conduction from the sinoatrial node to the av node. In these very rare cases, the treatment is usually a cardiac pacemaker. Otherwise the condition is of little to now concern.

A 44-year-old member asked:

Is it possible to fly if I have heart block?

1 doctor answer4 doctors weighed in
Dr. Martin Bress
Internal Medicine 50 years experience
It depends: There are several degrees of heart block. Third degree heart block usually causes very slow heart rates and can cause fainting or lightheadedness and is usually treated with a pacemaker. Lesser degrees of heart block usually cause no symptoms. It is ok to fly with a pacemaker but bring your pacemaker card with you as you may set off a metal detector. The low dose x-ray will image the battery.
