If you survive a cardiac arrest, you will be closely monitored in the intensive care unit. Your doctor will seek to determine what caused it and how you can prevent a reoccurrence.
Your doctor may recommend the following tests:
Blood test, which checks your levels of certain cardiac enzymes to determine if you have had a heart attack.
Chest X-rays, which check for other conditions that might explain your symptoms and to see if you have an enlarged heart.
Coronary angiography, a minimally invasive procedure to see how blood flows through your heart's arteries.
Electrocardiogram(ECG), which records your heart's electrical activity through electrodes (small, plastic patches that stick to the skin).
Testing for kidney, liver function, diabetes and cholesterol.
How is cardiac arrest treated?
Once you are rushed to the emergency room at the hospital, the medical staff will perform advanced life support resuscitation to stabilise your condition. Therapeutic shock and emergency medications may be given to stabilise your heart rhythm.
If you survive a cardiac arrest, your doctor will discuss with you the best treatment options to prevent a reoccurrence. These include:
Coronary angioplasty, a minimally invasive procedure that opens narrowed or blocked coronary arteries through a balloon (balloon angioplasty).
Corrective heart surgery, to correct a congenital heart deformity, faulty valve or diseased heart muscle tissue due to cardiomyopathy.
Implantable cardioverter-defibrillator (ICD), a battery-powered device implanted near your left collarbone. It monitors your heart rhythm and sends out energy shocks whenever it detects dangerous heart rhythm changes to reset your heart back to a normal rhythm.
Medications, such as beta blockers, anti-arrhythmic drugs, angiotensin-converting enzyme (ACE) inhibitors and calcium channel blockers.
Radiofrequency catheter ablation, where one or more catheters are threaded through your blood vessels to inside your heart to detect and block abnormal electrical pathways that may have triggered the cardiac arrest.
Even the fittest athletes can succumb to heart disease. Dr Leslie Tay, cardiologist, advises on reducing the risk of sudden cardiac arrest during sports.
