❤️‍🩹Electrocardiography: Principles and Practice

This chapter on electrocardiography aims to equip readers with the knowledge and skills necessary to understand and perform ECGs. It begins by explaining the electrical origins of ECG signals and the heart's conduction system, then correlates normal ECG features with cardiac activity. The text clarifies the purpose of 12 leads and their specific views of the heart, including Einthoven's triangle and augmented and precordial leads. Furthermore, it guides readers in recognizing dangerous arrhythmias and common ECG artifacts, concluding with instructions on operating an electrocardiograph and obtaining a proper tracing.
