Understanding an ECG | ECG Interpretation - Geeky Medics
网页2011年3月5日 · Each deflection (a.k.a. wave) on the ECG represents the average direction of electrical travel (calculated using the ECG machine’s mathematical formulae). The deflection height represents the amount of electrical activity flowing in that direction (i.e. the higher the deflection, the greater the amount of electrical activity flowing towards ...

Electrocardiogram (EKG, ECG) - CV Physiology
网页The different waves that comprise the ECG represent the sequence of depolarization and repolarization of the atria and ventricles. The ECG is recorded at a speed of 25 mm/sec (5 large squares/sec), and the voltages are calibrated so that 1 mV = 10 mm (2 large squares) in the vertical axis.
Electrocardiogram - StatPearls - NCBI Bookshelf
网页2023年6月5日 · The goal of the electrocardiogram interpretation is to determine whether the ECG waves and intervals are normal or pathological. Electrical signal interpretation gives a good approximation of heart pathology.
Conquering the ECG - Cardiology Explained - NCBI Bookshelf
网页The three waves of the QRS complex represent ventricular depolarization. For the inexperienced, one of the most confusing aspects of ECG reading is the labeling of these waves. The rule is: if the wave immediately after the P wave is an upward deflection, it is an R wave; if it is a downward deflection, it is a Q wave:

网页2011年2月28日 · 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. Heart rate calculation …
In brief: What is an electrocardiogram (ECG)? - National Center …
网页2023年6月6日 · If the heart is beating steadily, it will produce the typical ECG pattern: The first peak (P wave) shows how the electrical impulse (excitation) spreads across the two atria of the heart. The atria contract (squeeze), pumping blood into the ventricles, and then immediately relax.
