Tachycardia is a term of the mettle characterized by an unnatural rise in the heart rate more than normal while at eternal sleep . This experimental condition is marked by heart pace elevated above 100 beatnik per minute . Both physiologic and diseased grounds can be behind tachycardia . Tachycardia sometimes show up no symptom or complications . But if it is not handle decently , it may result in abnormal functioning of heart or serious knottiness such as heart nonstarter , cerebrovascular accident or cardiac catch or death .
What are the Main Causes of Tachycardia?
Tachycardia disease has fast heart rate than normal over 100 heartbeat per minute . In tachycardia , the heart chambers , upper or lower or both beat faster than normal and the heart has to put additional effort to pump blood , thus blood provision is compromise to the rest of the body and even to the heart itself . Tachycardia is caused when the electrical supplying to the heart bedchamber is disrupted from SA node , heart ’s pacer .
Tachycardia can occur due to physiological or pathologic reasons . Physiological reason can be exercise , gestation , anxiousness , malady or excitement i.e. jolt , fear or extreme joyousness .
The pathological cause of tachycardia are-
Tachycardia is categorized into following type according to descent and do of abnormally loyal heartbeat-
Atrial Fibrillation : The electric impulses that originate from upper chambers of the heart i.e. atria ensue in rapid , unpredictable and weak contractions of the atrium leading to increase nub charge per unit . Atrial fibrillation is the commonest type that is caused due to morphologic abnormality of the substance , heart valve disease , thyrotoxicosis or wakeless alcoholic drink maltreatment .
Atrial Flutter : Rapid heartbeat in atrial flutter is triggered by temporary circuit inside the atrium . In atrial commotion , heartbeat are very tight at a unconstipated rate . However , the episode of atrial disruption settee by itself without intervention in most of the case .
Supraventricular Tachycardia : When there is a sudden and abrupt rise in heartbeat more than normal , then the condition is know as supraventricular tachycardia . It stand up above the ventricles due to abnormal electric circuits in the heart . This circuit is created from the birth in the word form of overlapping signals .
Ventricular Tachycardia : The unnatural electric signals generated in the heart ventricle of the heart track to rapid heart charge per unit . This condition is termed as ventricular tachycardia . In this status , ventricles can not work on efficiently to pump enough blood to the rest of the body due to speedy meat rates . This may last in a couple of seconds . But it may prove fatal and life sentence - threatening if these episode last more than few seconds .
Ventricular Fibrillation : Ventricular fibrillation is triggered by speedy electrical whim mother in the modest chambers of the kernel . In this precondition , ventricle have to put extra efforts to ply blood and still it can not render sufficient rakehell to the whole body . If the affectionateness does not get back to its normal rhythm within few instant even with an electric shock , then the condition of the affected role becomes more calamitous . The main campaign of ventricular fibrillation are any underlying heart disease , or serious trauma , or lightning , or a spirit attack .
Conclusion
The rudimentary heart disease , high blood pressure , hyperthyroid , and other causes discussed above can chair to tachycardia . It should be managed properly in time to fend off life - menace complications .
