Incident Involving Rajesh Keshav


Rajesh Keshav, a prominent figure in the South Indian film industry, collapsed unexpectedly during an event in Kochi. Upon being rushed to the hospital, it was determined that he had suffered a cardiac arrest and is currently receiving ventilator support. This incident highlights the increasing occurrences of cardiac arrests.


What is Cardiac Arrest?

Cardiac arrest is a critical condition characterized by the sudden cessation of heart function. This occurs due to a malfunction in the heart's electrical system, leading to irregular heartbeats.


As a result of this malfunction, the heart fails to pump blood effectively, depriving the brain, lungs, and other vital organs of oxygen. This can lead to immediate unconsciousness and cessation of breathing. Without prompt medical intervention, death can occur within minutes.


Recognizing the Symptoms of Cardiac Arrest

Cardiac arrest typically strikes without warning, and its symptoms are severe. Key indicators include:


  • Sudden collapse and loss of consciousness.
  • Breathing may stop or become erratic.
  • No detectable pulse.
  • Immediate cessation of heartbeat.

Some individuals may experience warning signs such as chest pain, difficulty breathing, nausea, or a rapid heartbeat prior to fainting, but often there are no noticeable symptoms.


Distinguishing Cardiac Arrest from Heart Attacks

Heart Attack: A heart attack occurs when a blockage in the coronary artery prevents blood from reaching the heart muscle, causing damage. This condition is related to blood circulation.


Symptoms of a heart attack can include chest pressure, pain, sweating, shortness of breath, and discomfort in the jaw, neck, or left arm, which may last from minutes to hours. Typically, these symptoms develop gradually, and the individual remains conscious.


Importantly, the heart continues to beat during a heart attack.


Cardiac Arrest: In contrast, cardiac arrest is caused by an electrical issue within the heart. This leads to irregular heart rhythms and a complete halt in blood pumping.


Cardiac arrest occurs suddenly, resulting in immediate unconsciousness, cessation of breathing, and absence of a pulse.


Conclusion

In summary, understanding the differences between cardiac arrest and heart attacks is crucial for timely intervention and potentially saving lives.
