  At the beginning of systole, the balloon deflates; blood is ejected from the left ventricle, increasing the cardiac output by as much as 40 percent and decreasing the left ventricular stroke work and myocardial oxygen requirements. In this manner, the balloon supports the heart indirectly. Intra Aortic Balloon Pump, The 12-Lead ECG Summary,

  What is an EKG? The electrocardiogram (EKG) is a representation of the electrical events of the cardiac cycle. Each event has a distinctive waveform, the study of which can lead to greater insight into a patient’s cardiac pathophysiology. What types of pathology can we identify and study from EKGs?
