ECG Worksheet- Due to Unit 2 assignment box by 9/24 at 2200 A. 1. P waves are present and upright 2. PR interval: 6 small blocks x 0.04 = q 0.24 seconds (anything over 0.2 is high) 3. QRS: 1.5 small blocks x 0.04 = .06 (shld be between 0.06-0.12; more than 0.12 cld indicate PVC) 4. Rhythm: 4 big blocks x 0.2 = 0.8 (distance btwn Rs); equidistance = regular rhythm 5. Heart Rate: Big box method (reg rhythm): 300/ 4 big boxes btwn Rs = 75 bpm 6. First Degree AV Block B. 1. P wave: not visible 2. PR interval: not measurable 3. QRS: 1 small box x 0.04 = 0.04 (shld be between 0.06-0.12) 4. Rhythm (space btwn Rs): 2 big box, equidistance = reg rhythm 5. Heart Rate: Big box: 300/2 = 150 bpm 6. Paroxysmal Supraventricular Tachycardia C. 1. P wave: uneven fibrillatory waves 2. PR interval: not measurable 3. QRS complex: 1.5 small box 4. Rhythm: irregular 5. Heart Rate: 9 x 6 sec = 90 bpm 6. Atrial Fibrillation D. 1. P wave: absent 2. PR interval: not measurable 3. QRS: not measurable 4. Rhythm: irregular 5. Heart Rate: not measurable 6. Ventricular Fibrillation E. 1. P wave: present and upright 2. PR interval: inconsistent 3. QRS complex: normal width (x3), non-conducted QRS complex (x1) 4. Rhythm: irregular 5. Heart Rate: 4 x 60/3.6 = 67 bpm 6. 2nd Degree heart block, type 1 (Wenckebach) F. 1. SEE Figure A 2. 3. 4. 5. 6. H. 1. P wave: not measurable 2. PR interval: not measurable 3. QRS complex: wide and distorted 4. Rhythm: regular 5. Heart Rate 60/4.8 x 21 = 263 6. Ventricular Tachycardia I. 1. P wave: deep and inverted 2. PR interval: consistent; 1 big box 3. QRS complex: wide 4. Rhythm: regular 5. Heart Rate: 60/8.4 x 8 = 57 bpm 6. Ventricular bigeminy J. 1. P wave: present and upright 2. PR interval: inconsistent 3. QRS complex: normal 4. Rhythm: regular 5. Heart Rate: 3 x 10 = 30 bpm 6. 3rd Degree Heart Block K. 1. P wave: sawtooth pattern – more than QRS 2. PR interval: not measurable 3. QRS complex: normal 4. Rhythm: regular 5. Heart Rate: 60/4.8 x 7 = 88 bpm 6. Atrial Flutter L. 1. P wave: more than QRS 2. PR interval: normal 3. QRS complex: normal 4. Rhythm: irregular 5. Heart Rate: 7 x 10 = 70 bpm 6. 2nd degree heart block, type 2 M. 1. P wave: absent 2. PR interval: absent 3. QRS complex: absent 4. Rhythm: none 5. Heart Rate: none 6. Asytole
