Worksheet 1
Complete the basic measurements, diagnose RVH if the QRS direction is either rightward, anterior, or both, and evaluate clinically.

| SI/QT III pattern |
HR 75, sinus. PR normal. QRS 0.09, normal. Normal P and QRS direction. Q waves in leads V1 through V4 consistent with Q wave infarction, possibly old. There is a left atrial abnormality. The QRS voltage is high possibly representing LVH. There are nonspecific ST changes diffusely. (Check with straight edge.)

| SI/QT III pattern |
Sinus arrhythmia. Left atrial abnormality. LVH. Diffuse ST segment changes consistent with LVH or ischemia or infarction. ST elevation in V3 and V4 takes precedence (Third Rule of the T Waves).

| SI/QT III pattern |
Sinus rhythm at 71. SI Q III pattern suggests possibility of pulmonary embolism. Anterior T wave changes consistent with septal ischemia or infarction (First Rule of the T Waves), or acute pulmonary hypertension. The high QRS voltage in V3 and V4 may represent LVH as well.

| SI/QT III pattern |
Sinus tachycardia. HR 107. The QRS direction is rightward in lead I indicating RVH or LPHB. The QRS direction is anterior in V1 also indicating RVH. There are also voltage criteria for LVH. Leads V3 and V4 have tall R and S waves, which also suggest biventricular hypertrophy.
Worksheet 5

| SI/QT III pattern |
HR 88. Baseline artifact is present, but the rhythm is sinus. The PR interval is long, 1°AV Block. LVH with ST changes consistent with LVH ischemia or infarction.
