Explain the cardiac conduction cycle as shown on an EKG. What is the EKG? Explain the following waves and intervals: P-wave, P-R interval, QRS wave, S-T segment, QT interval and T wave. What does the QRS complex of an ECG represent? What is an E...
What are the peaks of an EKG? What do each of the peaks represent? Describe the electrical events occurring in the heart that are responsible for the P wave, QRS complex and T waves of the ECG. What is happening to the myocardium durin...
The waves or deflections shown on the ECG are named for the letters P, Q, R, S and T. R waves are the first upward deflection within a series known as the QRS complex. As part of the QRS complex, an R wave is an important indicator of cardiac health. Cardiologists and other ...
An EKG or ECG records the electrical activity of your heart. It may show abnormal heartbeats or signals from changes to the heart muscle. A chest x-ray will show enlarged ventricles or a large left atrium. An echocardiogram is a type of ultrasound. Sound waves are used to show the ...

An EKG records the electrical activity of your heart. It is used to check your heart rhythm and it may show if there is damage to your heart. An echocardiogram is a type of ultrasound. Sound waves are used to show the structure, movement, and blood vessels of your heart. An exercise ...
Sound waves can be used to show how well blood flows to and from your heart. Electrocardiogram (EKG) Small painless devices called electrodes can be put on your skin to check how well your heart is working. If this test is done in your doctor’s office, it will give a snapshot of yo...
You also might have regular X-rays if your doctor suspects the blow to your chest broke a bone. Your doctor also might order a stress test, which involves an EKG taken while you walk on a treadmill or pedal an exercise bike. What to Do When Commotio Cordis Happens ...
The heart is composed of the middle layer; the middle of the heart separates both parts of the heart to avoid the mix-up of the oxygenated blood and deoxygenated blood. The heart cavity is divided into four chambers composed of two atria and two ventricles....
Electrocardiogram (EKG or ECG)– Electrodes are attached to the skin on a person’s chest to track the strength and timing of the electrical activity of the person’s heart. Echocardiogram– High-frequency sound waves (i.e., ultrasound) are used to generate a picture of the inside and out...
