In this section we will be discussing the different cardiac dysrhythmias that lead to cardiac arrest, their characteristics, and the appropriate therapies to treat and correct the particular dysrhythmia. An ECG waveform represents each electrical event in the cardiac conduction system during a cardiac cycle. The P wave, which is the first waveform in the complete complex, followed by the QRS complex. The Q wave represents the first activity of the ventricular depolarization. The timeframe between ventricular depolarization and repolarization is indicated via the ST segment. We will use a systematic approach of looking at the rate, P wave, QRS, and T wave to interpret ECG rhythms. This training will help ACLS team members to efficiently, appropriately and effectively recognize cardiac dysrhythmias.
