Chapter 3 The Normal ECG and its (Normal) Variants

The shape of the electrocardiogram (EKG) tracing will exhibit certain key attributes to be considered normal, as discussed below.Medical Definition of Electrocardiogram Electrocardiogram: A recording of the electrical activity of the heart.The previous chapters reviewed the cycle of atrial and ventricular depolarization and repolarization detected by the ECG as well as the 12-lead system used to record this electrical activity.The ECG above is from a 74 years-old man with mitral stenosis, atrial fibrillation and hypertension.This is the second in a series of articles that aim to help readers to understand and interpret recordings of the surface ECG.

Every heartbeat is triggered by an electrical signal that starts at the top of your heart and travels to the bottom.An EKG is a measurement tool used to view the electrical activity of the heart.

By measuring the time interval of the ECG a doctor can determine how long it is taking an electrical wave to pass through your heart.

Learn about what conditions can be diagnosed through this test.

This has prevented the overlapping of ECG deflections in the precordial leads.

Sinus rhythm (as explained in the first section of this book chapter) is normal, meaning that the heart is depolarized by a wave starting in the sinus node.Basically you have a normal ECG reading according to the machine.The fact that the ekg and blood tests came back ok is a positive sign.

Normal EKG Flashcards | Quizlet

Each heartbeat consists of a P wave, a QRS complex, an ST segment, a T wave and U waves.Possible Cardiac Conditions Abnormal EKG results may indicate that your heart muscle is not getting an adequate supply of blood.At normal heart rates, this formula is clinically useful, but begins to underestimate and overestimate the duration of cardiac repolarisation at extreme low and high heart rates, respectively.17 In the presence of sinus arrhythmia, the interpreting physician should calculate an average QTc from analysis of the entire 12-lead ECG rhythm strip.28...A normal heart rate ranges between 50 and 100 BPM (beats per minute).

At the heart of ECG interpretation lies the ability to determine whether the ECG waves and intervals are normal.

ECG and EKG readings are painless and completely non-invasive.The ST segment is the part of the ECG between the end of the S wave and start of the T wave.

It is made up of waves displayed as a tracing on a metric grid.Abnormalities of the ST segment should be investigated to rule out pathology.An exercise electrocardiogram (EKG or ECG) is a test that checks for changes in your heart while you exercise.The electrocardiogram (ECG or EKG) is a noninvasive test that is used to reflect underlying heart conditions by measuring the electrical activity of the heart.

What can cause Abnormal ECG Results Posted on April 23, 2012 by favoriteplus You went to your doctor to pick up your ECG Test results and a technician in charge of the ECG gave you the results without telling anything except that your results are abnormal.While it is a relatively simple test to perform, the interpretation of the ECG tracing requires significant amounts of training.

Understanding an ECG | Geeky Medics

It is a recorded visual representation of the electrical impulses in the heart that make it beat.

It is used to record the electrical activity of the heart from different angles to identify and locate pathology.This book takes a logical and systematic approach to ECG interpretation, beginning with the basics of normal variations and dealing in turn with atrial abnormalities, ventricular enlargement, ventricular conduction defects and.An electrical impulse triggers every heartbeat, and this electrical impulse comes from special cells that are present in the upper-right heart chamber.Its normal value ranges between 0.12 s and 0.20 s. In cases such as Pre-excitation Syndromes, the PR interval could be shortened, it represents an accelerated AV conduction.

In cases such as First degree AV Block the PR interval is prolonged, so we say the AV conduction is delayed.Fusion beats - occur when a normal AV node beat fuses with a beat arising in the ventricles, causing a QRS complex halfway between normal and abnormal beat.So the first electrical signal on a normal ECG originates from the atria and is known as the P wave.
