Symptoms of 3rd degree block

Basically, 3rd degree block leaves the heart without a connection between atrium and ventricles. Since our natural pacemaker paces the atrium the ventricles are left on their own as to when to beat. The ventricles have a built in fall back rhythm that usual keep them beating at a slow 25-40 or so rate that is unchanged by exercise.

The symptoms can vary widely from just feeling a bit low energy to passing out. As J.B. mentioned it can also result in death if the rate is too low or the fall back is non existent. This is rare though and seems to be one of those fear tactics used to scare reluctant patients into have a pacer implanted. It's not uncommon for a patient to have to wait weeks or months to be scheduled for a pacer even with complete block.

Anyway, if you are in otherwise good physical condition and your fallback rate is in the 40 range, you may not even notice the problem. I was able to stand and walk around the night before implant with my HR down to 26, but the pacer made a very noticeable difference when they turned it on in the OR. I think you will be happy you have it.

Third Degree Heart Block Symptoms

You decide if you should have had symptoms.

The symptoms and severity of heart block depend on which type you have. First-degree heart block rarely causes severe symptoms.

Second-degree heart block may result in the heart skipping a beat or beats. This type of heart block also can make you feel dizzy or faint.

Third-degree heart block limits the heart's ability to pump blood to the rest of the body. This type of heart block may cause fatigue (tiredness), dizziness, and fainting. Third-degree heart block requires prompt treatment because it can be fatal.
