Full list of ECG results
Why a normal ECG has five visible waveforms–
Each portion of a heartbeat produces a different deflection on the ECG. These deflections are recorded as a series of positive and negative waves. On a normal ECG, there are typically up to five visible waveforms: P wave, Q wave, R wave, S wave, T wave.
How to recognize left bundle branch block–
Learn how to recognize a Left Bundle Branch Block (LBBB) in this video tutorial. After watching read and review this 12-Lead ECG case: Elderly man presents with CHF, hypertension and dyspnea.
12-lead ECG interpretation tips–
This four-step technique will help you interpret your 12-lead ECGs.
Basics of cardiac rhythm diagnosis–
If you are new to cardiac rhythm diagnosis or need of a thorough review, check out this detailed instructional video on the basics of rhythm diagnosis from Dr. Ken Grauer. Also view a video on the basics of supraventricular rhythms, including mechanism rhythms, AV nodal rhythms, AFib/AFlutter, MAT and PSVT.
Tip: Associate anatomical locations on a 12-lead ECG–
Use "Hooper's Trick" to associate leads and anatomical locations on a 12-lead ECG.
How to map an ECG–
See the heart graphically for better ECG interpretation.
A simplified method for 12-lead ECG electrode placement–
This example provides an alternative to the sternal notch placement of electrodes for acquiring a 12-lead ECG.
Also watch this popular video on how to map a 12-lead ECG to see the heart graphically for better ECG interpretation. And read about why we capture a 12-lead with the first set of vital signs.
EKG interpretation training review–
This five-minute video provides a quick overview of how to read an EKG
ECG Interpretation: Predicted Normal ECG - Chest Leads–
Using basic principles to easily predict the morphology of the ECG read-out in the 6 chest leads.
ECG Interpretation: Vectors: General Principles–
The electrical forces of cardiac depolarization and repolarization are vectors, and as vectors they obey certain mathematical principles.
ECG Interpretation: ECG Lead Perspectives–
The perspectives of the 12 ECG leads on cardiac depolarosiation and repolarisation, with the six chest leads examining the flow of cardiac depolarisation and repolarisation in the horizontal plan and a second group of six leads examining these events in the vertical plane.
ECG Interpretation: ECG Nomenclature–
The deflection produced by atrial depolarisation is termed a P wave while ventricular depolarisation produces the qrs complex. This teaches the correct nomenclature of individual deflections within the qrs complex and some important terms used in ECG analysis.
ECG Interpretation: Generation–
Leads capable of detecting electrical signal are placed on the patient's body and the different lead positions record and analyse the flow of current through the heart from different perspectives.
ECG Interpretation: Cardiac Electrical Activity–
The depolarisation and repolarisation waves spread through the heart in a highly predictable pattern and to understand the ECG readout, the pattern of spread of cardiac electrical activity needs to be understood.
ECG Interpretation: Predicted Normal ECG–
How to calculate the heart rate from an ECG in the presence of a regular and irregular heart rhythm.
