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 during (1) the PR interval and (2) the ST segmen
What is an EKG? An EKG, also referred to as an ECG, is an electrocardiogram, a measurement of the heart’s natural electrical activity. It is sometimes confused with an echocardiogram. Unlike the echocardiogram, which creates a visual representation of your heart using sound waves, an EKG spe...
200 for a 12-lead test. Being an engineer and inventor, I wanted to see if I could come up with a really good low cost way of designing and building my own unit so I could check out my own heart signals. The effort was
What does it mean to have an abnormal EKG? EKG results look like waves, going up and down as the heart contracts and pumps blood. Medical providers observe those wave forms to gauge how your heart is working. They are looking for a steady rhythm, demonstrating that all four chambers of ...
The T waves are also raised (in contrast to a STEMI, where the T wave remains the same size and the ST segment is raised). The ECG abnormalities do not change! During a STEMI, the changes will evolve – in benign early repolarisation, they will remain the same. ...
What does paroxysmal mean? sudden onset Identify rhythm on slide 62? Paroxysmal atrial tachycardia (PAT) Describe PAT? rate = >100 bpm paroxysmal = sudden onset P waves = visible and upright Identify rhythm on slide 63? wandering atrial pacemaker (WAP) ...
P waves may be superimposed on T waves in what sinus condition? Sinus tachycardia What defines a sinus pause? 1-2 beats are skipped What defines a sinus arrest? 3 or more beats are skipped What is the treatment for a sinus pause/ sinus arrest if the patient is symptomatic? Atropine and...
means heart) and EEG is an acronym to mean Electroencephalography (encephalo- means brain). EKG is just another term for ECG. This is because when it was being developed in Germany it was called EKG. ECG and EEG are staple diagnostic tests performed in the aspects of cardiology and ...
Repolarization is only electrical, and during that, the heart is at rest. Three major waves of electric signals appear on the ECG. Each one shows a different part of the heartbeat. The first wave is called the P wave. It records the electrical activity of the atria. The second and ...
called a bundle branch block. A complete lack of P waves, and in their place a squiggly line, combined with an irregular heartbeat is likely to be atrial fibrillation. What really gets a Paramedic or ER doctor excited is when they see an elevation of the ST segment in a few consecutive...
