Can you do an ECG on a patient with a pacemaker?

Monitoring a Pacemaker Patient The recommended lead placement for a pacemaker patient is as follows. A Pacemaker patient usually requires a different electrode patch placement configuration than a non-pacemaker patient. Do not place an ECG electrode directly over the pacemaker generator.

What is the S wave ECG?

The S wave is the first downward deflection of the QRS complex that occurs after the R wave. However, a S wave may not be present in all ECG leads in a given patient. In the normal ECG, there is a large S wave in V1 that progressively becomes smaller, to the point that almost no S wave is present in V6.

What does the T wave represent?

Introduction. The T wave on the ECG (T-ECG) represents repolarization of the ventricular myocardium. Its morphology and duration are commonly used to diagnose pathology and assess risk of life-threatening ventricular arrhythmias.

What does ECG look like with pacemaker?

PACEMAKER’S EFFECT ON AN ECG A paced rhythm is easy to recognize. When a pacemaker fires, a small spike is seen on the ECG. An atrial pacemaker will generate a spike followed by a P wave and a normal QRS complex.

Where are ECG leads placed with a pacemaker?

Pacemaker leads may be positioned in the atrium (upper chamber) or ventricle (lower chamber) or both, depending on the medical condition. If the heart’s rate is slower than the programmed limit, an electrical impulse is sent through the lead to the electrode and causes the heart to beat at a faster rate.

How is Vt different from SVT?

With a LBBB-like pattern, the presence of Q waves in V6 is indicative of VT. Note: SVT with LBBB is associated with absent Q waves in V6.

What are R waves?

The R wave is the first upward deflection after the P wave and part of the QRS complex. The R wave morphology itself is not of great clinical importance but can vary at times. The R wave should be small in lead V1.

What causes an abnormal T wave?

Transient T-wave inversion may occur in the following conditions: Acute coronary syndrome[1], cardiac memory T-wave[8,23], cardiogenic non-ischemic pulmonary edema[19], gastroenteritis[28], post maxillofacial surgery[29], subarachnoid hemorrhage[30], electroconvulsive therapy[31-33], Takotsubo cardiomyopathy[18,34].

When is a 12-lead ECG used?

Who should receive a 12-lead EKG in the first place? The primary purpose of the 12-lead EKG is to screen patients for cardiac ischemia, especially for acute ST-elevation myocardial infarction.

What is an ECG interpretation?

Think of it as 12 different points of view of an object woven together to create a cohesive story – the ECG interpretation. These 12 views are collected by placing electrodes or small, sticky patches on the chest (precordial), wrists, and ankles.

Where do you place leads for electrocardiography (ECG)?

For female patients, place leads V3-V6 under the left breast. Do not use nipples as reference points in placing electrodes for both men and women as nipple locations vary from one person to another. The 12 Lead Groups A lead is a glimpse of the electrical activity of the heart from a particular angle.

What are the areas represented on the ECG?

The areas represented on the ECG are summarized below: 1 V1, V2 = RV 2 V3, V4 = septum 3 V5, V6 = L side of the heart 4 Lead I = L side of the heart 5 Lead II = inferior territory 6 Lead III = inferior territory 7 aVF = inferior territory (remember ‘F’ for ‘feet’) 8 aVL = L side of the heart 9 aVR = R side of the heart

What are the best practices for performing an ECG?

ECG Best Practices: 1 Always protect the patient’s privacy and dignity by draping with a sheet to minimize exposure. 2 Lead placement and patient positioning should be the same for subsequent ECGs on any individual patient. 3 During the procedure, record any clinical signs (e.g. chest pain) in the notes or on the ECG tracing itself.
