Tachycardia and the most common causes

Tachycardia is a disorder of the heart rhythm; actually itis increased heart rate. There are many causes that can lead to tachycardia butthere are also factors that can worsen the already existing tachycardia and some ofthem are hypoxia, decreased level of oxygen, ischemia, acidosis, alkalosis, misbalanceof electrolytes, increased concentration of catecholamine in the blood, toxic effectof some medications, side effects of many drugs, excessive elongation of myocardiumfibers (heart muscle), presence of scars in heart tissue etc. As forconditions, all shock states have tachycardia as a compensatory effect, anaphylacticshock, septic shock, and bronchial asthma too. As for tachypnea, the onlysituation when tachycardia is normal and expected is during physical exertion.

Acute pancreatitis is one of the conditions that have tachycardia as a symptom. This illness is caused by auto digestion ofpancreatic cells by pancreatic enzymes. Shock occurs at one moment and that resultsin tachycardia. Pheochromocytoma is a tumor of adrenal gland that leads toincreased secretion of adrenaline and that will also cause tachycardia. Anothersymptom here is frequent blood pressure peaks.

What are other causes of tachycardia?

Rhythm disorders canbe present in cardiac arrest and tachycardia can be supraventricular andventricular. Sinusoidal tachycardia is a type of tachycardia that happensduring infract. Irritating sympathetic nervous system can be a direct cause of tachycardiabecause of the pain, fear and excitement. Some patients might have atrialtachycardia, which is a sign of complications that come after cardiac arrestand an obvious symptom of heart insufficiency. Cardiomyopathy is a disease of heart muscle that can causethree dysfunctions. One of those is dilatation of the heart cavities (dilatativecardiomyopathy), which is a consequence of acute viral myocarditis. Of course, one of the symptoms issinusoidal tachycardia.

It is important to mention some additional causes oftachycardia that are related to life habits. Smoking and nicotine in theorganism, obesity, taking a lot ofcoffee and alcohol, are all factors that easily induce tachycardia. Abusing drugs can alsoresult in tachycardia. Treating the condition that causes tachycardia willeventually return the heart rate into normal range. There is also aninteresting way of immediate help, which is not effective in all people thatsuffer from tachycardia. Pressing the eyeballs as hard as possible might pressvagus nerve, which might decrease heart rate. Of course, this is only temporarilyand only a real medical therapy can help completely.
