 | | The "good" cholesterol that promotes breakdown and removal of cholesterol from the body. | | | Also refers to a procedure that eliminates extra electrical pathways within the heart that cause fast or irregular heart rhythms. | | | A medication that opens up blood vessels, making it easier for the heart to pump blood forward to the body; also used to lower blood pressure. |

| Â | sinusbrady |
| | Sinus bradycardia occurs when the hearts rate is slower than 60 beats per minute. | | | The pulse volume may be greater due to a greater stroke volume and an increased diastolic run-off time (longer time for blood to flow away from the heart). |

| Â | ACC/AHA/ESC Guidelines for the Management of Patients with Atrial Fibrillation: Management |
| | Addition of an antiarrhythmic drug to enhance the likelihood that sinus rhythm will be restored and maintained may perturb the intensity of anticoagulation beyond the intended therapeutic range, raising the risk of bleeding or thromboembolic complications. | | | Thus, sinus rhythm can be restored in a substantial proportion of patients by direct-current cardioversion, but the rate of relapse is high unless concomitant antiarrhythmic drug therapy is given ( Figure 13). | | | These authors developed a scheme expressing the likelihood of success to facilitate clinical decision making and improve cost-effectiveness by avoiding cardioversion in patients unlikely to sustain sinus rhythm. |

| | There were 5 strokes in the atrial fibrillation patients discharged without coumadin and 4 strokes in the atrial fibrillation patients receiving coumadin at discharge. | | | During 15 years of follow-up, "only 2% of the sinus rhythm patients developed stroke, and none of those strokes occurred during the first 6 months postprocedure, the 'early stroke' that coumadin is supposed to prevent." | | | Gerald M. Lawrie, MD, clinical professor of surgery, Baylor College of Medicine, Houston, Texas, said that his institution is no longer requiring discharge coumadin therapy for patients who undergo mitral valve repair. |

| Â | Hospital Practice: Cardiac Arrhythmia |
| | If it is important to restore sinus rhythm sooner or anticoagulation therapy is contraindicated, a transesophageal echocardiogram can be performed to look for evidence of thrombus in the left atrial appendage. | | | Once sinus rhythm has been restored, physicians must decide whether to attempt to maintain sinus rhythm with antiarrhythmic drug therapy. | | | In the meantime, it is our practice to attempt to restore and maintain sinus rhythm in nearly every patient with atrial fibrillation. |

| | In patients with sinus bradycardia secondary to therapeutic use of digitalis, beta-blockers, or calcium channel blockers, simple discontinuation of the drug, along with monitored observation, often are all that is necessary. | | | In sick sinus syndrome, drug therapy approaches have been relatively disappointing. | | | Other causes of sinus bradycardia are related to increased vagal tone. |

| | Sometimes, cardioversion is done in conjunction with antiarrhythmic medications to reduce the likelihood of recurrence of the AF. | | | Persistent AF on the other hand, becomes the primary heart rhythm and it is usually unresponsive to medical therapy or other non-pharmacologic interventions such as electrical cardioversion. | | | This allows for maximal fine-tuning of the pacemaker to meet the needs of the patient. |

| | Specialized conduction pathways within the ventricle rapidly conduct the wave of depolarization throughout the ventricles to elicit ventricular contraction. | | | This intrinsic rhythm is strongly influenced by autonomic nerves, with the vagus nerve being dominant over sympathetic influences at rest. | | | This "vagal tone" brings the resting heart rate down to 60-80 beats/minute. |
