Peaked T-waves, flattened P-waves, and eventually a "sine wave" or widened QRS. Hypokalemia: and ST-segment depression. Hypercalcemia: Shortened QT interval. Hypocalcemia: Prolonged QT interval. Study Tips for the Final Watch the ChalkTalks: The exam format closely mirrors Dr. Nick’s Essential ChalkTalks ** Bazett’s Formula:** Be prepared to calculate the (Corrected QT) manually: Lead Placement:
: Review the rhythm strip and leads for general impressions. QRS Complex : Check for morphology changes and width ( is less than 0.12 s is normal). Regularity : Determine if the rhythm is regular or irregular. Ecg Academy Level 2 Final Exam Answers
Answer : An R wave greater than 11 mm in lead aVL. Peaked T-waves, flattened P-waves, and eventually a "sine
: Calculate heart rate and measure PR, QRS, and QT intervals. Axis and Voltage : Evaluate for deviation or hypertrophy. Pathological Q Waves : Look for evidence of past infarction. ST/T Abnormalities : Identify signs of ischemia or pericarditis. Anatomical Diagnosis : Correlate findings to specific cardiac regions. : Formulate the final diagnosis. For detailed practice, students frequently use the ECG Academy ChalkTalks Hypocalcemia: Prolonged QT interval
Look for high voltage (e.g., R wave in aVL > 11mm) and "strain patterns" (ST depression/T-wave inversion in lateral leads). Left Atrial Abnormality (LAA):
