Palpitations are basically due to problem of the heart’s rhythm. The cardiac rhythm is the electrical conduction that facilitates the heart to beat in a synchronous manner.
Heart palpitations are felt like rapid, pounding or fluttering beating of the heart. Not all palpitations are serious. Most of the times, they are quite normal and are falsely interrupted occasionally as extra heartbeats.
What causes heart palpitations?
Heart palpitations can be prompted by various factors including exercise, stress, medication or, infrequently, by a medical condition. An irregular heartbeat or arrhythmia is the most common heart condition that may cause palpitation and may require treatment.
The causes of heart palpitations can be usually classified into six major categories:
1. An overactive thyroid i.e. hyperthyroidism: It is a condition where your thyroid gland starts producing surplus thyroid hormone, which speeds up the body’s metabolism and causing an irregular or rapid heartbeat, irritability or nervousness.
2. Sympathetic nervous system over activation: A number of factors may lead to the stimulation of the sympathetic system with resultant onset of palpitations. These factors include hypoglycemia, panic disorders mitral valve prolapsed and thypoxia.
3. A cardiac dysrhythmia: This is a condition of irregular heartbeat which can cause heart palpitations. A number of dysrhythmias responsible for cardiac arrhythmias include supraventricular tachycardia, premature atrial contractions (PACs), ventricular fibrillation, atrial fibrillation (A-Fib), ventricular tachycardia and premature ventricular contractions (PVCs).
4. Hyperdynamic circulation or high circulatory volume. Hyperdynamic circulation is another factor that causes heart palpitations. The increase in circulatory volume may occur due to a number of reasons but the main etiologies are
· Pregnancy
· Anemia
· Strenuous Exercise
5. A deficiency of electrolyte, disorder or imbalance: There are several important electrolytes that function to maintain the normal body functioning. If any of these electrolytes get disturb with respect to their level, then functions of the body are affected as well as the heart which go off rhythm (that is heart palpitations ensue).
6. Parasympathetic nervous system overstimulation: The parasympathetic nervous system is responsible for control and regulation of the internal body glands and organs. When it is inappropriate stimulated, it can lead to inapt signals via the vagus nerve which moves via the heart and stomach. It can then lead to:
· Anxiety and Stress, which raises the levels of cortisol in the body
· Deficiency of Alkaline
· Gastrointestinal distress for example acid reflux, indigestion, or bloating
· Poor posture or muscular imbalances which can in turn further irritate the vagus nerve
And thus, eventually land up on causing heart palpitation.
