2 Ex 1Sinus because the SA node controls HRHeart Activity: P wave normal, followed by normal QRS, followed by normal T waveHR: 50 bpm and regularDiagnosis: Sinus (SA node) Bradycardia
3 Ex2 Heart Activity: Normal P wave, QRS dropped, Normal T wave HR: 50 bpmDiagnosis: Conduction problem, ventricles not contracting properly, needs pacemakerThis 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 bpmDiagnosis: Sinus Tachycardia
5 Ex 4 Heart Activity: Normal P wave, followed by QRS, normal T wave HR: 140 bpmDiagnosis: Sinus Tachycardia,
6 Ex 5Heart Activity: R to R interval too short and irregular, P wave not present in all beatsHR: 180 bpmDiagnosis: 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 wavePVC’s are identified by wide/bazaar QRS complexesP WavePVCQRSHeart Activity: PVC is present.HR: 30 bpmDiagnosis: 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 8Heart Activity: Frequent P wave, sometimes followed by QRS , normal T waveHR: 70 bpmDiagnosis: Atrial flutter (saw tooth pattern)
10 Ex 9 Heart Activity: No P wave, QRS is wide and T wave are present HR: 160 bpmDiagnosis: Ventricular tachycardiaAtria and ventricles are contracting at the same time
11 Ex 10Heart Activity: NormalHR: 110 bpmDiagnosis: Tachycardia
12 Ex 11Heart Activity: P wave is covered by T wave (would need to be measured with calipers)HR: 220 bpmDiagnosis: Supra ventricular tachycardiaSA 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
