19. Drug and Electrolyte Effects

In this material Self-study learning goals Define and identify EKG changes due to drugs: Digitalis. Sotalol. Amiodarone. Electrolytes abnormalities: Hyperkalemia. Hypokalemia. Hypercalcemia. Hypocalcemia. Drug effects  Digitalis Digitalis is one of the oldest and most commonly used cardiac medications. In therapeutic doses, digitalis effectively slows the SA node from firing as often, slows conduction through the […]

Right Ventricular Hypertrophy Worksheets

These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 18 Worksheets Make basic measurements and evaluate for ischemia, infarction, and atrial abnormality. Diagnose RVH if the QRS direction is either rightward, anterior, or both. Evaluate clinically.   Clinically-Based Critical Thinking: Interpretation Sinus tachycardia is present and represents […]

Right Ventricular Hypertrophy Case Studies

Case 1: Obstructive lung disease Tap the arrow to view the case.Obstructive lung disease (COPD), commonly caused by smoking, increases the pulmonary resistance to blood flow from the pulmonary artery. When the resistance to blood flow rises, the pressure builds up in the right ventricle. The increased pressure must be generated by the right ventricle, […]

18. Right Ventricular Hypertrophy

In this material Self-study learning goals Define and identify the following: The normal QRS direction. Describe the pathophysiology of right ventricular hypertrophy (RVH). List the two criteria for diagnosing RVH on the EKG. Identify RVH on the EKG. Describe and identify ST changes in RVH. Describe the EKG findings of RVH in chronic lung disease. […]

Left Ventricular Hypertrophy Worksheets

These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 17 Worksheets Make basic measurements and evaluate for ischemia, infarction, and atrial abnormality. Diagnose LVH if criteria listed in Chapter 17 are present. Evaluate clinically.   Clinically-Based Critical Thinking: Interpretation LVH is present by voltage since RI + […]

Left Ventricular Hypertrophy Case Studies

Case 1: ST segment changes in LVH Tap the arrow to view the case.In LVH (Figure 17.15), the ST segment may point opposite the mean QRS axis (Figure 17.16). This is sometimes referred to as “strain pattern.” These ST segment changes can be seen in the frontal plane, the horizontal plane, or both. In either […]
