A 65 year old man presents with a 3 day history of epigastric discomfort which he describes as severe indigestion associated with nausea and vomiting. He has a history of paroxysmal atrial fibrillation and takes digoxin for this. On examination, his height is 170 cm and weight 97 kg. His blood pressure is 110/70 mmHg and pulse 85/minute and regular. He has slight epigastric tenderness. His ECG is shown below:

An 89-year-old male presents for follow up of his persistent AF.

Successful cardioversion a month ago but recently reverted back to AF two weeks ago. Have been managed by warfarin, digoxin and diltiazem. He was previously prescribed metoprolol but had to stop due to side effects. He is entirely asymptomatic despite the inadequate rate control. He is not keen to take on more medications.

On physical examination, his blood pressure is 140/80 mm Hg and his pulse is 147/min. Cardiac auscultation reveals an irregularly irregular rhythm and a grade 2/6 pansystolic murmur. The lungs are clear to auscultation and there is no edema. Serum TSH is normal. A 24-hour ambulatory monitor demonstrates a mean heart rate of 137/min, with a minimum rate of 70/min and a maximum rate of 170/min.

Which of the following is the most appropriate management?

A 65-year-old man has a background of mild angina diagnosed a couple of years ago. He presents to the emergency department after 30 minutes of severe chest pain following some heavy physical activity. He has taken three glyceryl trinitrate tablet at home without relief. On arrival to the emergency department, he is given oxygen which gave him some relief. Over the last 6 months, his angina symptoms had been stable on atenolol 50 mg/day, aspirin and isosorbide mononitrate 60 mg/day. He has only experienced angina twice, and has not used his glyceryl trinitrate over this period.

What would be the most likely explanation for the failure of the glyceryl trinitrate to relieve his angina?

An 80-year-old woman with longstanding atrial fibrillation and hypertension sees a cardiologist in private for a second opinion on further management of her atrial fibrillation. She has been on metoprolol and had started on Warfarin a month ago. She is asymptomatic.

On examination, she has an apex rate of 60/minute and blood pressure of 136/84 mmHg. She has no signs of cardiac failure. An ECG confirms atrial fibrillation. A chest X-ray shows cardiomegaly with a cardiothoracic ratio of 14.5/28 but clear lung fields.

Echocardiography demonstrates left ventricular hypertrophy and diastolic dysfunction. Systolic function is preserved with fractional shortening of 28%. Atrial dimensions are normal.

Which of the following long-term management strategies is most appropriate?

There has been several randomized controlled studies comparing the use of anticoagulation compared with placebo in patients with nonrheumatic atrial fibrillation. These trials suggest that the annual risk of stroke in untreated patients with atrial fibrillation with a CHADs score of zero would be nearest to:

The electrocardiogram (ECG) shown above was performed on an asymptomatic 27 year old male

A 70-year-old woman is admitted to the hospital for intermittent dizziness over several days. There is no chest discomfort, dyspnea, palpitations, syncope, orthopnea, or edema. Had a CABG 6 years ago after a myocardial infarction. Background history includes hypertension, hyperlipidemia, and PAF with a history of rapid ventricular response. Her medications include metoprolol, simvastatin, cilazapril and warfarin.

On physical examination, her blood pressure is 135/88 mm Hg and her pulse is 52/min. Cardiac auscultation reveals bradycardia with regular S1 and S2, as well as an S4. A grade 2/6 early systolic murmur is heard at the left upper sternal border. The lungs are clear to auscultation. no pedal edema.
On telemetry, she has sinus bradycardia with rates between 40/min and 50/min, with two symptomatic sinus pauses of 3 to 5 seconds each.

Which of the following is the most appropriate management for this patient?

A 55-year-old man presents with recurrent arrhythmia. He went into rapid atrial flutter 6 weeks ago and underwent urgent cardioversion. He was later commenced on oral metoprolol.

Three days ago, he had a recurrence of his arrhythmia with worsening fatigue and has now begun experiencing dyspnea on exertion. There is no history of chest pain, lightheadedness, and palpitation.

He is otherwise fit and well and is only on aspirin and metoprolol.

On physical examination, his blood pressure is 120/60 mm Hg and his pulse is 50/min. BMI is 23. Cardiac examination reveals bradycardia with an irregular rhythm, normal S1 and S2, and no murmurs or gallops. Lungs are clear to auscultation.

The electrocardiogram shows atrial flutter with a 6:1 block and a ventricular rate of 50/min.

Which of the following is the most appropriate management for this patient?
