How to Read an Electrocardiogram (EKG/ECG) - Nurse.org
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.
ECG interpretation: Characteristics of the normal ECG (P-wave ...
At the heart of ECG interpretation lies the ability to determine whether the ECG waves and intervals are normal. This chapter will focus on the ECG waves in terms of morphology (appearance), durations and intervals.

2011年12月13日 · Characteristics of a normal ECG. Rhythm: sinus. Rate: 60-100 bpm. Conduction: PQ interval 120-200ms. QRS width 60-100ms. QTc interval 390-450ms (use the QTc calculator for this) Heart axis: between -30 and +90 degrees. P wave morphology:

2023年3月4日 · A normal ECG trace includes a P wave, a QRS complex and a T wave. A standard 12-lead ECG includes bipolar limb leads, unipolar limb leads and chest leads.
How to interpret the ECG: A systematic approach - ECG & ECHO
Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS complex; (3) the P-wave is positive in lead II and (4) the PR interval is constant.

2011年2月28日 · What is a normal adult heart rate? Normal: 60-100 bpm. Tachycardia: > 100 bpm. Bradycardia: < 60 bpm. Regular heart rhythm. If a patient has a regular heart rhythm, their heart rate can be calculated using the following method: Count the number of large squares present within one R-R interval. Divide 300 by this number to calculate heart rate.

By convention, the ECG tracing is divided into the P wave, PR interval, QRS complex, QT interval, ST segment, T wave, and U wave (see figure ECG waves). Electrocardiography (ECG) waves. P wave = activation (depolarization) of atria. PR interval =time interval between onset of atrial depolarization and onset of ventricular depolarization.

A standard ECG uses 12 electrodes (called a 12-lead ECG). These electrodes do not contain needles and are painless. If thick hair is present, the areas to which the electrodes are applied may first be shaved. These electrodes measure the magnitude and direction of electrical currents in the heart during each heartbeat.
