Question 1

Not in your case: In the absence of advanced heart disease it would be extremely rare. In a young female with no cardiac risk factors (diabetes, high blood pressure, cigarette smoking) not a problem. Try a clock radio with gentle music.

Question 2

im a 30 year on male just started hydrochlorothiazide for bp. and i noticed i had lots of panic type symptoms. fast heart beat (99bpm sitting) - feeling dizzy and faint. now i have this fear that it means cardiac arrest. health anxiety?

Accepted Answer

: When starting on anti hypertensives, the initial weeks may produce side effects which may include rapid heart rate, feeling dizzy, nausea, etc. This is a result of your blood pressure being lower. Your body initially tries to compensate for lower blood pressure by increasing the heart rate, it does lessen over time as your body adapts to the new "normal." These are not signs of cardiac arrest.

Accepted Answer

I : I am so sorry for your tragic loss.  Are you sure that the doctors didn't mean that he had a murmur in the past and that he was in asystole when the you found him?  If this is important for you to know, i'd hope your son's pediatrician would be able to clarify the situation for you.

Question 9

what actually happens physiologically in your heart during a?cardiac arrest?

Accepted Answer

Many options: Asystole , ventricular fibrillation, ventricular tachycardia, torsades DES pointes, . The ventricles fail to provide significant arterial flow to the aorta and the pulmonary artery, the systemic arterial pressure drops below critical level leading to cerebral hypoperffusion and syncope. If prolongued brain death occurs within 5 minutes at normothermia.

Question 10

is there brain function during a cardiac arrest?

Accepted Answer

For a brief time: When the heart stops circulating blood to the brain the functions of brain cease after about 5 minutes. If CPR is performed the brain function can return. However prolonged CPR may not get enough blood to brain to prevent brain damage even if heart recovers.
