Cardiac Arrhythmias For Dummies. Heart arrhythmias uh rith me uhs may feel like a fluttering or racing heart and may be harmless. This will essentially be the first part in our basi. The latter two are life threatening. In lesson three we start to take a look at a few of the basic arrhythmias in our ecg ekg interpretation.
In lesson three we start to take a look at a few of the basic arrhythmias in our ecg ekg interpretation. Normal cardiac impulses start there and are transmitted to the atria and down to the ventricles. It is located in the wall of the right atrium. Sinus rhythm is the normal regular rhythm of the heart set by the natural pacemaker of the heart called the sinoatrial node. These impulses stimulate and coordinate atrial and ventricular myocardial contractions that provide cardiac output. The three big ventricular problems you need to be aware of and understand for the physician assistant exam pance are premature ventricular contractions pvcs ventricular tachycardia and ventricular fibrillation.
It is located in the wall of the right atrium.
In lesson three we start to take a look at a few of the basic arrhythmias in our ecg ekg interpretation. These impulses stimulate and coordinate atrial and ventricular myocardial contractions that provide cardiac output. In normal adults the heart beats regularly at a rate of 60 to 100 times per minute. Sometimes the person can feel a skipped beat. Premature ventricular contractions premature ventricular contractions pvcs occur commonly. Heart rhythm problems heart arrhythmias occur when the electrical impulses that coordinate your heartbeats don t work properly causing your heart to beat too fast too slow or irregularly.
