The heart contains four main chambers with valves connecting each chamber. The chambers are named the left and right atrium and the left and right ventricle.
An electric signal that originates withing the right atrium is the cause for the heart to even function the way it does. All thanks to our natural pace maker.
Another effective piece of equipment is a device called a defibrillator. This device helps stop the heart in order to give it a chance to get back on rhythm.
Many patients that suffers from heart attacks have to take medication in order to make sure their hearts are in working order. Medications like blood thinners help the patient in a stable condition after surgery.
