In medical sense, a person’s pulse refers to the throbbing of their arteries as a consequence of the pumping of his or her heart. Pulse can be felt at the wrist, and also at certain other points of the body.
Pulse is caused by pressure waves that are produced as the blood gets ejected into the aorta with every contraction of heart. After the ejection, there occurs a natural expansion in the aorta.
Increased pulse rate can be due to a variety of reasons. The most commonly seen reason for a high pulse rate is anaemia or low blood counts. It is also advisable to check the functioning of your thyroid gland along with the blood test.
The condition of fast paced heartbeat is referred to as tachycardia. Normally, the reasons for this condition gets classified under two heads, namely, sinus related and non-sinus related.
Sinus tachycardia relates to that condition in which a person’s heart beats comes to more than hundred in one minute. The irregularity is found to originate from the sinus node. It can be either appropriate or inappropriate. Anxiety, panic, dehydration, decrease in blood due to bleeding, loss of other body fluids, hyperthyroidism, electrolyte abnormalities etc can all result in appropriate sinus tachycardia. Inappropriate sinus tachycardia gets confirmed when all the possible causes of the appropriate version is ruled out. The root cause behind inappropriate sinus tachycardia is not yet clearly known but it is found to occur when the sinus node gets depolarised. This causes an increased sensitivity to adrenaline. If the symptoms are not very much concerning no treatment needs to be done. In most cases, people resume their normal life if no other symptoms are seen. In cases of intolerable symptoms, medical care needs to be provided.
Nonsinus tachycardia can either be supraventricular (coming from the upper heart chambers) or ventricular (coming from the lower heart chambers) in nature. Among them, ventricular tachycardia results in more serious consequences as rapid depolarisation of the ventricles take place.
