Cardiac Arrest

The most common cause of a lethal dysrhythmia is by a PVC hitting the peak of the T wave (known as R-on-T Phenomenon). This causes a pulseless shockable or non-shockable rhythm in at risk patients. 90% of cardiac arrests in adults are shockable (Pulseless VTach/Ventricular Fibrillation). This rhythm started with multifocal PVCs to a wide complex tachycardia (Pulseless VTach). This can only last from a few seconds to a few minutes before it becomes Coarse Ventricular Fibrillation (if no CPR and Defibrillatory shocks were administered). Coarse VFib can only last for about 4-5 minutes before it becomes Fine VFib. From then on, you have seconds for Fine VF to become Asystole.

yes you can bring a patient back from a flat line. You just have to get to them and you got 2 minutes to start CPR or they will be brain dead.

If I had a choice in the way I go out I'd choose cardiac arrest. My father described his experience as painless and it felt like he just went to sleep, with of course the highly intense bright light of being shocked back to life.

@music4ismylife8 the must conition cause of cardiac arrest is by a pvc hiting the t wave of by death of heart mususle from blockage.

[tingmarco1]

the contion is that your cardic musules get tired when you a dead.

after years of immense work and nonstop exercise the heart decided it was time to rest and thus it never beated ever again....

It's sad to see such an awesome simple organ just come to a rest

@TheTxturtlelytiger You don't. You never shock when the heart flatlines, you do CPR and epinephrine to stimulate the heart. Try doing a bit of research before you tell the correct guy he is wrong.

@icunurse01 im a paramedic. you should check your facts.

i restored a pulse on a 85 year old man (witnessed arrest) last week and no cpr was done before we got there, and it took us 6 minutes to get there.

8 minutes is the best guess by the american heart association, provided they are in the care of medical staff.

the most common cause of cardiac arrest is an infarct (death of heart muscle by way of a blockage) in one of the arteries of the heart. this lack of bloodflow to the heart aggitates the heart muscle and it quivers -like shaking a bowl of jello. it no longer ejects blood to the brain and other vital organs, or only delivers a minimal amount of blood to the tissues. there are many other causes, but MI is the most common.

i thought the preface to this video should be corrected..
