Pace maker - Study guides, Class notes & Summaries

Autorythmic - Answer Self Exciteable, and repeatedly generate action potential eg. natural pace maker Cause of fundamental heart rhythm - Answer NOT by nerve impulses or hormones, rather electrical impluse SA Node - Answer Main natural pacemaker, faster conduction than autorhytmic fibres The Heart's electrical flow - Answer SA Node to AV Node - AV Node to AV Bundle - Bundle of HIS to L and R branches to Apex and Purkinje FIbres (which then cause systolic phase and ventricle con...

A candy maker makes two sizes of candies. Using the smaller size, a full jar will contain 120 pieces of candy. Using the larger candies a jar will contain 80 pieces of candy. The candy maker has a strict rule that no jars will contain a mix of small and large candies. If a store has room for 15 jars and they want 1560 total pieces of candy, how many jars will contain smaller candies? - Answer x = smaller size y = larger size 120x + 80y = 1560 x + y = 15 3x+2y = 39 2x+2y = 30 x...

DEPOLARIZATION correct answers Movement of ions (Na+, Ca+, K+) across cell membrane causing inside of cell to become more positive, electrical conduction results in contraction. Na+ channels open. Positive inside, negative outside. REPOLARIZATION correct answers movement of ions across cell membrane where inside of cell is restored to its negative charge. Sodium channels close. Potassium channels open. Active transport by sodium-potassium pump DEPORIZATION correct answers ELECTRICAL CON...

Pace Maker of the Heart - Answer-The Sino Atrial node is also known as the 100/60 -138/89 - Answer-Normal BP range is -0.1 eV for each box in the vertical direction -typically there are 10 boxes in the vertical direction for QRS complexes, adding up to 1.0 eV - Answer-The vertical lines in each of the boxes indicate: Coreg and epinephrine - Answer-What medication can change Atrial fibrillation to a sinus rhythm? 140-250 bpm - Answer-What is the heart rate with a SVT? -Stimulate t...

P wave - Depolarization of the atria PR interval - -Normal is 0.12 to 0.2 seconds - onset of atrial depolarization until onset of ventricular polarization QRS complex - -Normal is 0.06 to 0.11 seconds -Ventricular depolarization -systole T wave - -appears after QRS complex - Ventricular repolarization -Spiked T-wave occurs with hyperkalemia U wave - - repolarization of the purkinje fibers - seen in patients with hypokalemia SA node - the pace-maker of the heart; where the impulse cond...
