By measuring your heart’s electrical activity, an EKG can detect if your heartbeat is regular, irregular, too fast or too slow. It can also indicate if your heart is overworked. This information can be especially important if you are preparing for surgery …

2024年8月9日 · Use this EKG interpretation cheat sheet that summarizes all heart arrhythmias in an easy-to-understand fashion. One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart’s electrical activity as waveforms.

2025年2月24日 · An electrocardiogram measures the electrical activity of the heartbeat. With each beat, an electrical wave travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on an EKG will show the rate and rhythm of the contractions in the upper and lower chambers. EKG strip showing a normal ...

2024年4月2日 · An electrocardiogram (ECG or EKG) is a quick test to check the heartbeat. It records the electrical signals in the heart. Test results can help diagnose heart attacks and irregular heartbeats, called arrhythmias. ECG machines can be found in medical offices, hospitals, operating rooms and ambulances.

2023年6月6日 · Heart conditions such as heart attacks or irregular heartbeats can be detected in ECGs. They can help us find out what the underlying causes are. The QRS complex between the P wave and the T wave in a normal heartbeat. What does the test involve?

2024年8月23日 · Being able to read an EKG or ECG is an important skill for nurses. But looking at a 12-lead EKG/ECG can put your own heart into a lethal rhythm. Nurses are usually the first ones to read that “hot off the press” EKG tracing. This article will explain everything you need to know about EKG readings. What is an EKG?

2024年11月6日 · Understanding how to interpret an EKG can provide valuable insights into heart health and help detect a range of cardiac abnormalities. For healthcare professionals and students alike, mastering EKG interpretation requires a solid grasp of foundational concepts and systematic practice.

2011年2月28日 · Cardiac axis describes the overall direction of electrical spread within the heart. In a healthy individual, the axis should spread from 11 o’clock to 5 o’clock. To determine the cardiac axis, you must look at leads I, II and III. Read our cardiac axis guide to learn more. Typical ECG findings for normal cardiac axis:

2021年9月13日 · To read an EKG, it’s important to understand the components of the wave. The P-Wave records the electrical activity through the upper heart chambers. It represents atrial depolarization, or contraction. The PR interval spans from the beginning of atrial depolarization (P-Wave to the beginning of ventricular depolarization (QRS Complex).
