How to help someone who is unconscious?
If you see someone collapse, seek emergency medical help immediately. Follow these steps: 1 Call 911 or your local emergency number. 2 If the person is unconscious, check for a pulse. 3 If no pulse, begin CPR to help keep blood flowing through the body until an automated external defibrillator (AED) is available. The American Heart Association recommends hands-only CPR. Push hard and fast on the person's chest — about 100 to 120 times a minute. It's not necessary to check the person's airway or deliver rescue breaths. Continue until emergency medical help arrives. 4 Use an AED as soon as it's available. Deliver a shock following the prompts on the device.

What is an ICD device?
Implantable cardioverter defibrillator (IC D). A surgeon places this device inside your chest or belly. When your heart is out of its regular rhythm, it gives high- or low-energy electrical shocks to get your heartbeat back to normal. (If your ventricles start to quiver, it will deliver a high-energy shock.)
What is the best treatment for acute heart failure?
Interventions for acute heart failure include administering a rapid-acting diuretic, such as furosemide (Lasix), to reduce preload. Interventions also typically include placing the patient in the high-Fowler position rather than the supine position.
What is the recommended energy level for a biphasic defibrillator?
If a biphasic defibrillator is used to manage a patient with stable, monomorphic ventricular tachycardia, the recommended energy level is 100 joules. The recommended energy level for supraventricular tachycardia and atrial flutter is 50 to 100 joules. The level for atrial fibrillation is 120 to 200 joules.
What is premature atrial complex?
Premature atrial complexes are ectopic beats that are initiated by an irritable atrial focus. P waves are present, but because the ectopic focus originates the impulse outside the sinoatrial node, the premature P waves have a different configuration. Atrial flutter causes no P waves, but it causes flutter waves in a sawtoothed pattern.
