- Hypoxia or the lack of adequate oxygen supply in the body leading to heart palpitations shortness of breath.
- The use of antihistamines such as Levocetirizine also triggers heart palpitations.
- Anemia or the lack of sufficient volume of blood in the body.
- Junctional Escape beat, a condition arising out of delayed heartbeat.
- Abnormal heart rhythm may lead to cardiac arrhythmia which is also known as atrial fibrillation.
- A type of premature heartbeat palpitation or irregular heart beat characterizes a cause of heartbeat palpitation.
- Heart beat palpitations are also caused by Premature Ventricular Contraction which is actually triggered by heart ventricles rather than by senatorial node. This is also known as PVC heart palpitations.
- Fast pace of heart rhythm caused in one of the ventricles of the heart is known as Ventricular tachycardia. Such cases of high paced heart beat may jeopardize one’s life leading to ventricular fibrillation.
- The operation of the heart beats in a tachycardic rhythm leads to Supraventricular tachycardia that originates in the ventricular tissue.
- The blockage of the electrical conduction system of the heart is known as a heart block which can be the cause for heart beat palpitations.
Other causes for Heart Palpitations
- Heart palpitations during and after exercise naturally increases the pace of heart beat leading to pounding heart palpitations.
- Along with the, strong emotional feelings characterized by fear, anxiety, stress, depression or nervousness also contribute to the racing heart palpitations.
- Medications like asthma drugs and inhalers to treat breathing problems, diet pills to control diet, beta blockers, thyroid pills used to treat an underactive thyroid, anti-arrhythmics needed to treat an irregular rhythm of the heart.
- Alcohol, caffeine and marijuana heart palpitations is caused by the use of stimulants such as amphetamines, cocaine, alcohol, adrenaline, nicotine, caffeine, marijuana and other illegal drugs. Besides these, the medicines available over the counter such as decongestants and nutritional supplements also cause heart palpitations.
