Can all components be identified in each beat? (Can you each wave, complex, segment, and interval?) If no, which are missing? • Are the intervals between each component and each complex consistent? If no, which are inconsistent? • Are there clear abnormalities of any of the wave components? If yes, which are abnormal

### Second Degree Block The image illustrates an electrocardiogram (ECG) graph showing a second-degree heart block. This condition is characterized by intermittent disruptions in the transmission of electrical signals from the heart's atria to the ventricles. #### Graph Explanation: - **Vertical Axis:** Represents the electrical activity (voltage) of the heart. - **Horizontal Axis:** Represents time. - **Key Features:** - The graph shows repeating patterns with one or more missing QRS complexes (the spikes representing ventricular contractions). - These missing beats indicate a blockage in the heart's electrical conduction system. - Notice the irregularity in the spacing between QRS complexes, which is a hallmark of this type of block. Second-degree heart block can be categorized into two types: Mobitz Type I (Wenckebach) and Mobitz Type II, each with distinct patterns. This graph likely represents one of these types, illustrating the concept of atrioventricular conduction delay.
