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.
Causes of heart palpitations. Heart palpitations are frequently caused by stress or anxiety. In addition to making you feel terrible emotionally, stress can have a physical effect on your body. As a result, stress can cause the nerve endings that control your heart to fire more frequently or irregularly. Anxiety and panic attacks can also trigger palpitations by elevating adrenaline levels. Food and drink can cause heart palpitations. Caffeine, nicotine, and alcohol can all affect your heart rate and may also increase the likelihood of irregular heartbeats. Some medications can cause heart palpitations. These include asthma inhalers, over the counter medications such as pseudoephedrine, and thyroid medications.
