SCD (Sudden Cardiac Arrest) leads to unexpected death. Sudden Cardiac Arrest is such a malignant health condition that patients need emergency treatment to restore the blocked heart rhythm.
In most cases of sudden cardiac arrest, the chances of survival of patients are zero, as it is caused by long-term blockage of heart functions. After sudden cardiac arrest, if patients survive the event, their quality of lifestyle is damaged. Dozens of health crisis such as brain injury, neurologic dysfunction, and neurocognitive deficiency affects the whole physical & psychological well-being of the patients who survive after sudden cardiac arrest.
So, people should be aware of the hidden & malignant causes behind sudden cardiac arrest to ensure the longevity of their lives. If they become familiar with the signalling system of the heart, they can opt for precautions to avoid life-threatening sudden cardiac arrest.
Causes Behind Sudden Cardiac Arrest
Ventricular Fibrillation
Ventricular fibrillation is a crucial health condition that leads to the rapid & irregular contraction of lower heart chambers. Due to Ventricular fibrillation, the abnormal signalling system of the heart leads to random quivering of lower heart chambers. So, VF(Ventricular Fibrillation) causes a chaotic signalling system, which creates a sensation in the myocardium instead of the coordination in the heart’s contractions. In this condition, the heart fails to pump blood and circulate blood to the different organs and brain. As a result, the heart fails to produce regular & average output for healthy blood circulations throughout the body.
Finally, VF leads to sudden cardiac arrest.
Coronary Artery Disease
The high amount of cholesterol deposits in the arteries leads to arterial blockage and hinders the spontaneous blood flow from the heart to other organs. So, heart muscle dysfunction, caused by reduced blood flow in the clogged arteries, leads to sudden cardiac arrest.
Extreme Physical Stress
Back-to-back dynamic physical activities increase the production of Adrenaline hormones in the body. As a result, a massive amount of Adrenaline triggers arrhythmia limits the isometric contraction phase, increases the systolic pressure, and reduces the diastolic pressure. In simple words, excess Adrenaline leads to a “fight or fight response boosting the heartbeats”. All these alterations in body functions affect the direct blood flow in the heart and cause sudden cardiac arrest.
Lack of Body Minerals
Lack of Potassium
While the other body mineral – Potassium level drops- it makes the heart rhythms irregular, which also causes sudden cardiac arrest.
Conclusion
All the discussed points explain how critical dysfunction in the heart due to internal health issues can lead to sudden heart failure. Therefore, people who have common heart problems should be careful about their lifestyle recommendations by doctors, as they can avoid such reasons of sudden cardiac arrest.
