Tachycardia is defined as an excessive rapid heartbeat in association with an irregularity in the rhythm, force and sustainability of heartbeats. Human heart is categorised in to a two stage electric pump which carries out a job circulating blood through the entire body. The initial process or electrical impulse generally begins the process of a heartbeat when generated by a cluster of cells situated in the atrium, the upper chamber of the heart. These are the automatic pacemakers commencing the electric signal by spreading along in the veins in the heart muscles creating a co-ordinated squeeze that affects the part of pumping function.
Human heart is of four chambers, the upper one, the right , left atria and the lower chamber with the right and left ventricles. The right side of the human heart pumps blood to the lungs whereas the left one pumps it to the entire body.
Tachycardia or heart rhythm disorder is a malfunction of the electric system of the heart. The condition affects the normal rhythm of the heart depending on the difficulty; the heart may beat too fast or too slow. In short, it is the irregularity of the heartbeat. This disorder is often referred as a severe cardiac syndrome where in many cases the heart beat is not observed at all which is fatal.
Medically also known as cardiac arrhythmias, it is an abnormal behaviour of heart in concern with its rhythm i.e force, pace and beats. The condition majorly occurs because of the problems that are directly associated with the electric wiring, this issue can also be developed influencing on the conducting system from outside of the heart.
Causes of Heart Rhythm Disorder or Tachycardia
The condition is majorly observed because of the problem a person has in terms of weak heart function or in born heart related complications. It is a problem within the heart itself, which gives rise to the rhythmic disorder by gradually stepping up by creating irregularity in heartbeats.
It is majorly caused due to the body’s inability in concern with body’s environment affecting the ability of the human heart to conduct the electricity required. In occurs when the cardiac or heart muscles get irritated after depletion from oxygen. This process majorly occurs during heart attack when the coronary arteries supply the blood gets blocked.
Secondly, the decrease in oxygen carrying capacity of the blood can be one of the major reasons causing and increasing the risks of heart rhythm disorder. Wiring problems with the electric pathway in the heart increase the risks of rapid heart rates miserably. This abnormality can be observed due to difficulty in physical extra electrical pathway or WPW syndrome or in the case of atrial flutter.
Rapid heart rates can also be caused because of environmental issues directly affecting heart. This can be intrinsic or extrinsic. Existing health conditions like anemia, abnormal electrolyte levels or abnormal thyroid levels are also considered to be the major reasons as the cause of Tachycardia.
Excessive consumption of caffeine, alcohol, stimulats, or over the counter cold remedies etc are some of the causes increasing the risks for heart rhythm disorders.
Signs and symptoms of heart Rhythm Disorders or Tachycardia
The symptoms are internal and in many of the cases it becomes difficult to understand and recognise them because of the lack of physical existence. In most of the cases, the patient is unaware of the heart rhythm disturbances a person can experience. Premature atrial contractions (PACs) and premature ventricular contractions (PVCs) are some of the normal or regular variations most often people are unaware that an extra beat has occurred. On the contrary, some patients are keen on their awareness of any extra heartbeat in such cases. It is a normal variant which requires no treatment.
Dysrhythmia is amongst the initial symptom which is often characterised under palpitation or with the sensation that the heart is beating too low, or faster or irregular. Such cases are intermittent and require proper medical assistance to maintain sustainability.
The other symptoms in consideration to Heart Rhythm Disorders include light headedness, weakness, nausea, chest pain, vomiting and shortness of breath. In some of the critical cases, the patient may fail to the ground or lose complete consciousness; this can be a life threatening complication which needs to be necessarily worked out.
How is heart rhythm disorder diagnosed?
The EKG and heart rhythm monitoring is the basic method of diagnosis as far as the condition prevails. These methods are done immediately in the ambulance or upon the arrival in the emergency department.
Moving on depending on the associated symptoms and the history of the patients and under complete observation and monitoring of the heart is generally carried out in hospital or as an outpatient. A heart monitoring device is normally used to make a complete diagnosis. In some cases, the rhythm identification is elusive and requires months or years to capture the perfect identity.
Once the rhythm is known, the medical tests further identify the potential cause of the condition. A specific rhythm abnormality including perfect blood tests and lung evalution is also carried out.
Treatment for heart Rhythm Disorders or Tachycardia
There is no single treatment treating the condition of heart rhythm disorder or abnormality. The treatment is generally carried out when the patient is unstable with reduced pulse or blood pressure or when the patient is in the unconscious state. For V-Fib and V-tach, electricity is considered as the most important drug. The process involves shock treatments, where the heart is shocked back in to a heart rhythm making it compatible with life.
In terms of medications, there are varieties of them available in the category of epinephrine, adrenalin, atropine and amiodarone. Considering the health and further complexities, intolerances and sensitivities of the patients, the medications and their dosage may vary. After a complete analysis, a medical representative will provide the patient with a proper and reliable medical dose which helps them maintain the heart beat and rhythm in regularity.
