• Tall and peaked P wave
• Hypertrophy of the atrial wall
• Why would this be happening
• >.25mV
• Could have tricuspid stenosis—remote chance
• Pulmonary stenosis—pressure in the Right ventricle from the blood not leaving—possibly esp. if >30 y/o
• Lung damage w/fluid accumulation—40 and 50's years—the blood leads to capillaries in the alveoli—pulmonary hypertension
• Leads to Right Ventricular hypertrophy and Right Atrial hypertrophy
• P. pulmonale
• RVH—right ventricular hypertrophy
• CHF—congestive heart failure
• Edema, swollen ankles, veins of neck—backs up to the venous system—
• Emphysema
• 300 boxes/min, 5 boxes/sec
• The height of one box is .5mV
• Most P waves are about half the height of a box
• Normal voltage for a P wave is .25mV

• Curvy and long P wave or two humps w/in one box
• Left atrial enlargement—P-mitrale
• Mitral stenosis
• Atrial flutter—saw tooth looking figures
• Atrial fibrillation—quivering line then a QRS wave
• b blockers to block the sympathetics that are going to the heart
