Sample Name: Paroxysmal Atrial Fibrillation
Description: A middle-aged white female undergoing autologous stem cell transplant for multiple myeloma, now with paroxysmal atrial fibrillation.
(Medical Transcription Sample Report)
INDICATION: Paroxysmal atrial fibrillation.
HISTORY OF PRESENT ILLNESS: The patient is a pleasant 55-year-old white female with multiple myeloma. She is status post chemotherapy and autologous stem cell transplant. Latter occurred on 02/05/2007. At that time, she was on telemetry monitor and noticed to be in normal sinus rhythm.
As part of study protocol for investigational drug for prophylaxis against mucositis, she had electrocardiogram performed on 02/06/2007. This demonstrated underlying rhythm of atrial fibrillation with rapid ventricular response at 125 beats per minute. She was subsequently transferred to telemetry for observation. Cardiology consultation was requested. Prior to formal consultation, the patient did have an echocardiogram performed on 02/06/2007, which showed a structurally normal heart with normal left ventricular (LV) systolic function, ejection fraction of 60%, aortic sclerosis without stenosis, a trivial pericardial effusion with no evidence for immunocompromise and mild tricuspid regurgitation with normal pulmonary atrial pressures. Overall, essentially normal heart.
At the time of my evaluation, the patient felt somewhat jittery and nervous, but otherwise asymptomatic.
PAST MEDICAL HISTORY: Multiple myeloma, diagnosed in June of 2006, status post treatment with thalidomide and Coumadin. Subsequently, with high-dose chemotherapy followed by autologous stem cell transplant.
ALLERGIES: NO KNOWN DRUG ALLERGIES.
1. Acyclovir 400 mg p.o. b.i.d.
2. Filgrastim 300 mcg subcutaneous daily.
3. Fluconazole 200 mg daily.
4. Levofloxacin 250 mg p.o. daily.
5. Pantoprazole 40 mg daily.
7. Investigational drug is directed ondansetron 24 mg p.r.n.
FAMILY HISTORY: Unremarkable. Father and mother both alive in their mid 70s. Father has an unspecified heart problem and diabetes. Mother has no significant medical problems. She has one sibling, a 53-year-old sister, who has a pacemaker implanted for unknown reasons.
SOCIAL HISTORY: The patient is married. Has four adult children. Good health. She is a lifetime nonsmoker, social alcohol drinker.
REVIEW OF SYSTEMS: Prior to treatment for her multiple myeloma, she was able to walk four miles nonstop. Currently, she has dyspnea on exertion on the order of one block. She denies any orthopnea or paroxysmal nocturnal dyspnea. She denies any lower extremity edema. She has no symptomatic palpitations or tachycardia. She has never had presyncope or syncope. She denies any chest pain whatsoever. She denies any history of coagulopathy or bleeding diathesis. Her oncologic disorder is multiple myeloma. Pulmonary review of systems is negative for recurrent pneumonias, bronchitis, reactive airway disease, exposure to asbestos or tuberculosis. Gastrointestinal (GI) review of systems is negative for known gastroesophageal reflux disease, GI bleed, and hepatobiliary disease. Genitourinary review of systems is negative for nephrolithiasis or hematuria. Musculoskeletal review of systems is negative for significant arthralgias or myalgias. Central nervous system (CNS) review of systems is negative for tic, tremor, transient ischemic attack (TIA), seizure, or stroke. Psychiatric review of systems is negative for known affective or cognitive disorders.
VITAL SIGNS: She is afebrile at 97.4 degrees Fahrenheit with a heart rate ranging from 115 to 150 beats per minute, irregularly irregular. Respirations are 20 breaths per minute and blood pressure ranges from 90/59 to 107/68 mmHg. Oxygen saturation on room air is 94%.
HEENT: Benign being normocephalic and atraumatic. Extraocular motions are intact. Her sclerae are anicteric and conjunctivae are noninjected. Oral mucosa is pink and moist.
NECK: Jugular venous pulsations are normal. Carotid upstrokes are palpable bilaterally. There is no audible bruit. There is no lymphadenopathy or thyromegaly at the base of the neck.
CHEST: Cardiothoracic contour is normal. Lungs, clear to auscultation in all lung fields.
CARDIAC: Irregularly irregular rhythm and rate. S1, S2 without a significant murmur, rub, or gallop appreciated. Point of maximal impulse is normal, no right ventricular heave.
ABDOMEN: Soft with active bowel sounds. No organomegaly. No audible bruit. Nontender.
LOWER EXTREMITIES: Nonedematous. Femoral pulses were deferred.
LABORATORY DATA: EKG, electrocardiogram showed underlying rhythm of atrial fibrillation with a rate of 125 beats per minute. Nonspecific ST-T wave abnormality is seen in the inferior leads only.
White blood cell count is 9.8, hematocrit of 30 and platelets 395. INR is 0.9. Sodium 136, potassium 4.2, BUN 43 with a creatinine of 2.0, and magnesium 2.9. AST and ALT 60 and 50. Lipase 343 and amylase 109. BNP 908. Troponin was less than 0.02.
IMPRESSION: A middle-aged white female undergoing autologous stem cell transplant for multiple myeloma, now with paroxysmal atrial fibrillation.
Currently enrolled in a blinded study, where she may receive a drug for prophylaxis against mucositis, which has at least one reported incident of acceleration of preexisting tachycardia.
1. Atrial fibrillation. The patient is currently hemodynamically stable, tolerating her dysrhythmia. However, given the risk of thromboembolic complications, would like to convert to normal sinus rhythm if possible. Given that she was in normal sinus rhythm approximately 24 hours ago, this is relatively acute onset within the last 24 hours. We will initiate therapy with amiodarone 150 mg intravenous (IV) bolus followed by mg/minute at this juncture. If she does not have spontaneous cardioversion, we will consider either electrical cardioversion or anticoagulation with heparin within 24 hours from initiation of amiodarone.
As part of amiodarone protocol, please check TSH. Given her preexisting mild elevation of transaminases, we will follow LFTs closely, while on amiodarone.
2. Thromboembolic risk prophylaxis, as discussed above. No immediate indication for anticoagulation. If however she does not have spontaneous conversion within the next 24 hours, we will need to initiate therapy. This was discussed with Dr. X. Preference would be to run intravenous heparin with PTT of 45 during her thrombocytopenic nadir and initiation of full-dose anticoagulation once nadir is resolved.
3. Congestive heart failure. The patient is clinically euvolemic. Elevated BNP possibly secondary to infarct or renal insufficiency. Follow volume status closely. Follow serial BNPs.
4. Followup. The patient will be followed while in-house, recommendations made as clinically appropriate.
