ECG 101

Course overview

Course Objectives: 1.List the different waveforms on an ECG, their physiological correlation and additional investigations that may be needed. 2.Discuss the different atrial and ventricular arrhythmias that can be visualized on an ECG. 3.Describe the use of ECG to assess MI, heart blocks and hyperkalemia. Abstract The key to reading an ECG is practice, practice and more practice. There is no substitute for practice. Because even the normal ECG tracing can be somewhat variable, it is vital to know what a normal ECG looks like before one can start to analyze the strip for any cardiac disorders. The critical component of the ECG that needs to be understood is the P-QRS-T waveform. Needs Assessment ECG is a valuable investigative tool for many cardiac disorders. However, it should never be used alone to make a diagnosis of any specific medical disorder. ECG is usually used in combination with clinical findings, laboratory data and imaging studies to rule in a particular medical disorder, like an MI. Even though ECG is preferentially read by physicians, allied healthcare workers play a vital role in obtaining studies to compliment ECG-thus, an interprofessional approach to reading the ECG is vital. Basic knowledge of ECG is vital for paramedics, ER personnel and nurses.
