Heart block typically causes lightheadedness, fainting, and palpitations. Depending on the severity of the heart block, this can be dangerous. For example, a third-degree heart block can worsen pre-existing conditions, such as heart failure. It can cause loss of consciousness and even sudden cardiac arrest. There can also be chest pain.
Heart rhythm problems can cause the feeling that the heart is âracing,â (palpitations), weakness, passing out (syncope), and sometimes death. Blockages in the coronary arteries can also cause major problems in the heart because they slow or stop the flow of blood to the heart muscle. If the heart does not get enough blood, pain (often called angina) or muscle death from a heart attack (myocardial infarction) can result.
