EKG - answer
calculate heart rate ekg - answer
small box - answer 0.04 S
5 small row box = 1 large box - answer 0.20 S
30 large boxes - answer = 6 seconds
Potential causes for dysrhythmias: - answer ●MI - elevated troponins
●Electrolyte imbalances (Know those lab values, and how they affect
rhythms)
,●Hypoxia
●Drug toxicity
●Hypovolemia
●Trauma to heart muscle/Cardiac surgery
●Exercise/normal autonomic response
more info: - answer Know the lab values most likely to affect cardiac
muscle including K, Mag and Calcium.
H&T's:
- Hypovolemia, Hypoxia, Hydrogen ion (acidosis), Hyper-/hypokalemia,
Hypoglycemia, Hypothermia.
- Toxins, Tamponade(cardiac),Tension pneumothorax, Thrombosis
(coronary and pulmonary), and Trauma.
Cardiac Output - answer = Heart Rate x Stroke Volume
What is the patients MAP if BP is 110/70? - answer 83
70 x 2 +
MAP formula: - answer Diastolic x 2 + systolic / 3
Normal sinus rhythm (NSR) - answer - Rate: Atrial and ventricular rate of
*60-100 bpm*
- Rhythm: Atrial and ventricular rhythms are regular
- P wave: Present. There is one P wave before each QRS complex
- PR interval: 0.12-0.20 seconds
- QRS complex: 0.04-0.10 seconds
, Sinus Arrhythmia - answer - Rate: Atrial and ventricular rates of *60-100
bpm*
- Rhythm: Atrial and ventricular rhythms irregular
- P wave: Present. One P wave before each QRS complex
- PR interval: Normal. 0.12-0.20 seconds
- QRS complex: Normal 0.04-0.10 seconds
*A variant of normal sinus rhythm that can occur in healthy adults during
inspiration*
Sinus Bradycardia - answer - Rate: *Less than 60 bpm*
- Rhythm: Regular
- P wave: Present
- PR interval: Normal
- QRS complex: Normal
Brady info: - answer s/s:
●Sometimes there are none
●Can be normal in extremely athletic patients
●Nausea, dizziness, vomiting, diaphoresis, difficult to arouse
tx:
●Depends on symptoms
●Atropine - 0.5 mg IV every 3-5 minutes as needed
●If ineffective - may add Dopamine or epinephrine
●Pacing
○Transcutaneous
Permanent pacemaker
*If patient is symptomatic, we need to speed things up! *Symptoms can be
very similar to hypoglycemia - we are not meeting the metabolic needs of
the brain
