1. What’s Wrong With My Patient?

2. Ex 1
Sinus because the SA node controls HR
Heart Activity: P wave normal, followed by normal QRS, followed by normal T wave
HR: 50 bpm and regular
Diagnosis: Sinus (SA node) Bradycardia

3. Ex2 Heart Activity: Normal P wave, QRS dropped, Normal T wave
HR: 50 bpm
Diagnosis: Conduction problem, ventricles not contracting properly, needs pacemaker
This person feels fine and does not detect a problem. This was an incidental finding that would eventually become a problem later on.

4. Ex 3 Heart Activity: Normal P wave, followed by QRS, S-T is inverted
HR: 120 bpm
Diagnosis: Sinus Tachycardia

5. Ex 4 Heart Activity: Normal P wave, followed by QRS, normal T wave
HR: 140 bpm
Diagnosis: Sinus Tachycardia,

6. Ex 5
Heart Activity: R to R interval too short and irregular, P wave not present in all beats
HR: 180 bpm
Diagnosis: Atrial fib

7. Ex 6 Heart Activity: QRS interval too long HR: 50 bpm
Diagnosis: Sinus bradycardia with a heart block

8. Ex 7 Heart Activity: PVC is present. HR: 30 bpm
T wave
PVC’s are identified by wide/bazaar QRS complexes
P Wave
PVC
QRS
Heart Activity: PVC is present.
HR: 30 bpm
Diagnosis: Sinus rhythm with PVC, area of ventricles are irritable and sending reverse conduction signals, both the SA node and the ventricles are sending a signal

9. Ex 8
Heart Activity: Frequent P wave, sometimes followed by QRS , normal T wave
HR: 70 bpm
Diagnosis: Atrial flutter (saw tooth pattern)

10. Ex 9 Heart Activity: No P wave, QRS is wide and T wave are present
HR: 160 bpm
Diagnosis: Ventricular tachycardia
Atria and ventricles are contracting at the same time

11. Ex 10
Heart Activity: Normal
HR: 110 bpm
Diagnosis: Tachycardia

12. Ex 11
Heart Activity: P wave is covered by T wave (would need to be measured with calipers)
HR: 220 bpm
Diagnosis: Supra ventricular tachycardia
SA node is generating impulse too quickly, ventricles do not have time to completely reload.

13. Ex 12 Heart Activity: Normal HR: 90 bpm
Diagnosis: Normal heat activity

14. Ex 13 Heart Activity: Quivering HR: None Diagnosis: V Fib
In reality the leads were not connected to your patient
