EKG interpretation style guide
memorize this Instructions and examples Instructions for Chapter 4 Worksheets Count the number of small boxes between two QRS complexes. Divide that number into 1500 to accurately determine the HR. Use the HR to classify the rhythm as sinus rhythm (60 to 100), sinus tachycardia (greater than 100), or sinus bradycardia (less than 60). Provide […]

Clinical Conditions that Affect the EKG Worksheets
These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 20 Worksheets Make basic measurements, evaluate for ischemia, infarction, and hypertrophy. Diagnose clinical conditions based on criteria described in Chapter 20. Evaluate clinically. Clinically-Based Critical Thinking: Interpretation There is sinus tachycardia associated with low voltage. Possibilities include […]
Clinical Conditions that Affect the EKG Case Studies
Case 1: Low voltage: Pneumothorax Tap the arrow to view the case.A pneumothorax occurs when air seeps into the pleural space. The air interferes with the negative pressure in the pleural space and causes the lung to collapse. A pneumothorax can occur spontaneously (without any specific cause). It can also occur secondary to some form […]
20. Clinical Conditions that Affect the EKG
In this material Self-study learning goals Define and identify the associated EKG changes for: Pneumothorax. Pleural effusion. Dextrocardia. Pericardial effusion. Infiltrative cardiomyopathy. Pericarditis. Dilated cardiomyopathy. Hypertrophic cardiomyopathy. Chronic obstructive lung disease (COPD). Athlete’s heart. Describe possible EKG changes associated with: Postoperative patients. Cancer patients. Overview The electrocardiogram (EKG) not only provides valuable information on the […]
Drug and Electrolyte Effects Worksheets
These worksheets are for self-study only. Answers will not be evaluated. Instructions and examples Instructions for Chapter 19 Worksheets Make basic measurements, evaluate for ischemia and infarction, evaluate for hypertrophy. Diagnose drug and electrolyte abnormalities as appropriate based on the heart rate, QRS, QTc, and ST segments. Evaluate clinically. Clinically-Based Critical Thinking: Interpretation Sinus […]
Drug and Electrolyte Effects Case Studies
Case 1: Hyperkalemia progression and reversal Figure 19.6b demonstrates very wide QRS complexes that measure 0.20 seconds. This is not a typical bundle branch block because it is so wide. The T wave is tall wide and bizarre as well. Any QRS of 0.20 seconds suggests hyperkalemia until it is ruled out. Figure 19.6c was […]
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 […]
