The P-wave is generated by depolarization (activation, contraction) of the atria. This approach always reveals something about an ECG, regardless of how unusual it is A normal ECG trace includes a P wave, a QRS complex and a T wave. Before A GENERAL PRACTITIONER’S GUIDE TO INTERPRETING ECGSThe basics of interpreting an ECG. The interpretation of any ECG should start by confirming the patient’s identity, time and date of the ECG, and whether the patient experienced any chest pain when the ECG was taken. Understanding these essential elements of the normal lead Interpreting the ECG. A normal ECG tracing is provided in FigureThe only way to become confident at reading ECGs is to practice. These patterns of continuity and discontinuity are clinical-electrographically defined as tracé discontinu, aroundtoorweeks, with quiet periods of voltage An electrocardiogram is also known as an ECG; the Dutch and German version of the word, elektrokardiogram, is shortened to EKG. It is a tool used to visualize, or “gram,” the electricity, or “electro,” that flows through the heart, or “cardio.” Specifically, a lead ECG tracing shows how the depolarization wave, which is a wave of positive charge, moves ECG interpretation starts with assessment of the P-wave and PR interval. The PR interval determines whether impulse transmission from atria to ventricles is normal ECG recording technique that results in incorrect ECG recording Evidence indicates that appropriate training leads to fewer ECG recording errors While these guidelines generally apply to the hospital/clinicalmade as comfortable as possible and the ECG trace annotated with an appropriate explanation if it is suboptimal quality. The PR interval is the interval between the start of the P-wave and the start of the QRS complex. An ECG rhythm strip or lead ECG can be printed to view and measure the electrical activity of the heart A standard lead ECG includes bipolar limb leads, unipolar limb leads and chest leads An electrocardiogram (ECG) records the electrical potentials via electrodes placed on the chest wall. It is important to be methodical – every ECG reading should start with an assessment of the rate, rhythm, and axis. This should be followed by checking the calibration of the ECG. The standard speed setting ismm/second cardiac electrical activity and relates this to the appearance of the normal lead ECG. We will define key terms, discuss the factors that determine the orientation of the QRS complex, and consider how to determine the cardiac axis.
