Dysrhythmias * they can result in deviations from a normal HR and/or rhythm, causing decreases in cardiac output. Some dysrhythmias are lethal, causing a complete loss of CO, which result in cardiopulmonary arrest. Other dysrhythmias are apparent on ECG's but are symptomless correct answer: Disruptions in the cardiac conduction pathway or disorders of the electrical impulse conduction within the heart HR x SV = CO HR is how many times the heart beats per minute; SV is the amount of...

What is the Suzuki method? ️ The Suzuki method empathizes memorization and repeatedly playing the same music. It is based in the theory that kids learn to speak before they can read. What tool is most appropriate for a 4th grade music teacher to assess students playing ability? ️ Providing students with self assessment scoring rubric. What factors should a 4th grade teacher take into account when qualitatively measuring a text's complexity? ️ The literal and inferential levels of ...

Dysrhythmias week 2 Week 2: Dysrhythmias • Dysrhythmias and arrythmias mean the same thing • Abnormal cardiac rhythms are termed dysrhythmias. • Prompt assessment of dysrhythmias and the client’s response to the rhythm is critical. Properties of Cardiac Cells • AUTOMATICITY-ability to initiate electrical impulses spontaneously and continuously (without thinking about it- SA node working (primary pacemaker) • EXCITABILITY- ability of cardiac cells to respond to electrical act...

Reading Specialist Latest Update Graded A+ Stop Sounds Stop sounds are phonemes we can't hold. "C" is an example of a stop sound. We can't hold "C." "D" and "G" are stop sounds. Sometimes students (and teachers) forget to clip stop sounds. Instead of "d," they say "du." Instead of "g," they say "gu." This can cause confusion. A student may say "duogu" for dog. After the student reads "duogu" they, unsurprisingly, can't figure out that the word is actually "dog....

electrical properties of the heart - Answer-1-automaticity 2-excitability 3-conductivity 4-contractility automaticity - Answer-=the ability of cardiac cells to depolarize spontaneously w/o external stimuli -cells able to modify membrane to pull in Na+ while K+ exits -rapid depolarization when threshold potential is reached -only certain cells have property of automaticity: SA node, AV node, bundle of HIS, purkinje network influence of the nervous system - Answer-SYMPATHETIC: affects ...

Automaticity Correct Answer (pacing function) is the ability of cardiac cells to generate an electrical impulse spontaneously and repetitively. Excitability Correct Answer the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells and depolarize Conductivity Correct Answer ability to send an electrical stimulus from cell membrane to cell membrane. Contractility Correct Answer the ability of atrial and ventricular muscle cells to shorten t...
