Heart Block: The term heart block does not relate to blockages in the arteries of the heart, but to block in the flow of electrical current in the electrical conducting system of the heart. Heart block results in slow heart beats, which may give rise to severe dizziness or syncope (passing out). But heart block is not the usual cause of dizziness, which has many other causes.

Heart block: Heart block is an electrical phenomenon of interrupted conduction of electrical impulses in a component of the hearts electrical conduction system. There are partial and complete forms of block in the atrioventricular pathway. Complete av block causes a dissociation of atrial and ventricular electrical activity. The symptoms are those of very slow heart rate, lightheaded, weak, dizzy and sob.

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.

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.
