Bradycardia is defined as heart rate less than 50 beats per minute. This rhythm is too slow to maintain an adequate blood pressure. 2. The patient must be symptomatic, exhibiting one or more of the "unstable" signs/symptoms related to the slow rate. 3. Bradycardias range from sinus bradycardia to complete, third degree heart block. First-Degree AV Block - ✔✔This block is caused by a delay in the passage of the impulse anywhere from the atria to the ventricles. It is characterized by a long PR interval (more than 0.20 seconds) that is constant. Second-Degree AV Block, Type I (Wenckebach): - ✔✔This block occurs when some impulses are conducted and others are blocked. It is characterized by progressive prolongation of the PR interval until a P wave is not conducted. This pattern is repetitive and results in "group beating". ex: 3 conducted P waves with progressively lengthening PR intervals and a 4th P waves that is not followed by a QRS Second-Degree AV Block, Type II: - ✔✔This block occurs when some impulses are conducted and others are blocked. It is usually associated iwth a lesion in the conduction pathway. It is characterized by constant PR intervals in conducted beats and more than one non-conducted P waves. This block, when associated with an acute myocardial infarction (AMI) carries a high risk of progressing to a complete heart block. Third-Degree AV Block (Complete Heart Block) - ✔✔This block indicates complete absence of conduction between atria and ventricles. The atria and ventricles are depolarized from different pacemakers and b. If ventricular rate is more than 150, synchronized cardioversion at 200 joules. c.

If hypotension occurs and no evidence of congestive heart failure (CHF), give 250ml NS IV/IO (or LR if currently infusing) f. 12 lead ECG (assists in decision making, classification and treatment approach. ST segment elevation of more than 2mm in 2 contiguous leads or the onset of a new BBB suggests STEMI. Goal for ST elevation myocardial infarction (STEMI) is percutaneous coronary intervention (PCI) or thrombolytics in less than 90 minutes. If ECG is suggestive of STEMI, call RRT (STEMI Algorithm) Symptomatic hypotension - ✔✔Generally defined as SBP less than 90mmHg. The reduced BP produces clinical signs or tissue hypoperfusion. Clinical manifestations differ according to cause and compensatory mechanisms in effect. Clinical signs that may indicate inadequate tissue perfusion include cool, clammy skin, oliguria, increased heart rate (cardiac compensation), impaired sensorium (decreased level of consciousness, confusion) *The patient must be symptomatic, exhibiting one of more of the 'unstable' symptoms related to the hypotension If hypotension/shock is associated with an arrhythmia: - ✔✔Rate that is too fast or too slow- treat the rhythm not the hypotension/shock Treatment for hypotension due to hypovolemia - ✔✔Fluid replacement *Vasopressors play a secondary role to increase systemic vascular resistance (when circulating volume is adequate) Hypotension that occurs post anesthesia: - ✔✔Treated with fluid replacement and Ephedrine Treat symptomatic hypotension with: - ✔✔a.

Cardiovascular collapse is a common manifestation caused by vasodilatory and loss of plasma from blood compartment. Epinephrine Severe Anaphylaxis - ✔✔Considered to be the most important drug for any severe anaphylactic reaction. It works best when given early after the onset of reaction.
