Av node rate 40 60 bpm Study guides, Class notes & Summaries

Conduction System of the Heart correct answers The SA (sinoatrial) node spontaneously generates impulses at a rate of 60-100bpm This stimulates the atria to contract and travel to the AV node The signal gets briefly held in the AV node and is then conducted through the bundle of His, Purkinje fibers and the ventricular epicardium If the SA node can't fire the AV junction will take over at a rate of 40-60bpm If both the SA and AV junction don't fire the ventricles generate an impuls...

3 pacemakers of the heart - 1. SA node 2. AV node 3. bundle branch intrinsic rate of SA node - 60-100 bpm intrinsic rate of AV node - 40-60 bpm intrinsic rate of bundle branches - 20-40 bpm electrical pathway through the heart - 1. normal conduction impulse originates in the *SA Node* 2. impulse travels to *AV Node* causing atrial depolarization (contraction)

normal specific gravity correct answers 1.010-1.030 polyuria correct answers 2,500 mL/24hr Oliguria correct answers <400mL/24hr Anuria correct answers <100mL/24hr Serum Creatinine (SCr) correct answers 0.6-1.2 mg/dL somewhere around 1 Normal Urea correct answers 10-20mg/dL Normal BUN correct answers 10-20 mg/dL Normal BUN:Creatinine ratio correct answers 6-25 normal BUN is 10-20 normal creatinine is 0.6-1.40 so 10-20:0.6-1.40 is the ratio I think. so either 10...
