Q

A 65-year-old man presents to his local GP for a screening ultrasound scan. He has been feeling well and in his usual state of good health. His medical history is notable for mild hypertension and he has a 100-pack-year tobacco history. On palpation, he has a large pulsatile mass just below his umbilicus.

Q

A 55-year-old man with a history of hypertension (well controlled with medication) and tobacco use presents to his primary care physician with a 2-day history of constant and gnawing hypogastric pain. The pain has been steadily worsening in intensity. He says the pain radiates to his lower back and both groins at times. While he cannot identify any aggravating factors (such as movement), he feels the pain improves with his knees flexed. There is a palpable pulsatile mass just left of midline below the umbilicus. He is immediately referred for definitive management, but during transfer becomes hypotensive and unresponsive.

A 62-year-old man is referred for management of atypical multiple myeloma. He has a mild anaemia of 120 g/L (12 g/dL), a urinary protein loss of 2.2 g/day with a urinary immunofixation showing free lambda light chains. However, the bone marrow shows only 5% plasma cells and does not fulfil criteria for multiple myeloma.

Q

A 70-year-old woman with a history of hypertension, diabetes mellitus, hyperlipidaemia, and prior myocardial infarction presents to the emergency department with palpitations and shortness of breath. These symptoms started 2 days ago. She was diagnosed to have AF with rapid ventricular rate response a year and a half ago, at which time an attempted direct current cardioversion and a trial of sotalol to maintain sinus rhythm and prevent further episodes of AF were unsuccessful. The patient was treated with digoxin and metoprolol to control rate and warfarin to prevent stroke. Current physical examination shows that she is febrile and has an irregularly irregular radial pulse at a rate between 90 and 110 bpm, BP 100/70 mmHg, and respiratory rate of 26 breaths per minute. Heart sounds are irregular, but no S3 or S4 gallop or murmurs are audible. The breath sounds are of bronchial character associated with crepitations over left basal lung area.

A

SVT

57
Q

A 78-year-old man was diagnosed with left-sided systolic heart failure 14 years ago. He was subsequently found to have atrial fibrillation, and underwent AV node ablation and pacemaker placement 10 years ago that resulted in an improvement in his left ventricular ejection fraction from 35% to 50%. He did extremely well over the years and was extremely active; 3 years ago he completed a 210-mile bike ride across the Netherlands. Four months ago, however, he started developing chest tightness and back tightness when pulling his cart during golfing sessions. In addition, he developed significant dyspnoea with activity and his symptoms have worsened. Now, he says his quality of life is extremely poor. He has problems walking up one flight of stairs where he experiences significant shortness of breath; even walking half a block causes shortness of breath and chest tightness. He has also noticed increased abdominal girth, early satiety, and easy fatigue.

A 73-year-old woman presented for the first time 5 years ago with worsening shortness of breath and lower extremity oedema. On clinical examination, she has a laterally displaced apical impulse, with a loud 3/6 holosystolic murmur at the apex. Jugular veins are distended to the angle of the jaw. Lung examination shows some bibasilar crackles. There is 2-3+ pitting oedema in both lower extremities.

A 45-year-old woman presents with complaints of heaviness and fatigue in her legs. She does not experience the symptoms when she first awakens, but they become more noticeable and prominent as the day progresses and with prolonged standing. When she is standing for most of the day she notes swelling in both legs. The symptoms are concentrated over her medial calf, where she has prominent tortuous veins. She first noted dilated veins about 20 years ago when she was pregnant. Initially they did not cause her any discomfort but they have progressively enlarged and over the past 10 years have become increasingly painful. She recalls that her mother had similar veins in her legs.

An 18-year-old man presents to a clinic reporting 2 episodes of loss of consciousness. The first episode occurred 1 year earlier while playing dodge ball in gym class. He recalls diving to the ground to avoid being hit. On getting up quickly, he noticed feeling lightheaded, sweaty, and nauseated. Apparently, he fell to the ground but does not recall having done so. He later recalls waking up in an accident and emergency (A&E) department. Witnesses reported shaking and clenching of both hands after he had fallen. In the A&E department he was given phenytoin intravenously because of concern that he may have had a seizure. After a negative work-up in the hospital he was prescribed carbamazepine, despite no abnormalities on an electroencephalogram. A year later he had a second episode of loss of consciousness while doing bicep curls. He denies palpitations, tongue biting, or incontinence. He experienced a similar prodrome of warmth and lightheadedness.

Vasovagal syncope

Q

A 60-year-old man presents with syncope while walking outside with his wife. His wife recalls the patient looking at the sky to point out an aeroplane. He then appeared pale and collapsed to the ground, suffering a head laceration in the process. The history suggested the possibility of carotid sinus syndrome (CSS). In the laboratory, carotid sinus massage was undertaken while the patient was in the upright posture on a tilt table. The massage induced 10 seconds of asystole with near loss of consciousness. A dual-chamber pacemaker was implanted on the basis of a presumptive diagnosis of CSS; there was no recurrence of syncope during the next year. This patient has had no further faints but occasionally becomes dizzy when turning his head abruptly (CSS).

An 88-year-old bed bound female presents with a large weeping, scaly lesion on her left heel. On closer inspection it is covered with slough and contains white fibrotic areas. It is noted that she also has bilateral ankle swelling and varicose veins in her left popliteal fossa.

A 68-year-old man with a history of smoking and long QT syndrome is rushed to A&E following a sudden collapse. He is tachycardic and his ECG shows absent QRS complexes.

Ventricular fibrillation

64
Q

A 65-year-old man has a history of prior anterior wall MI that occurred 2 years ago, complicated by severe left ventricular systolic dysfunction. While walking to the shops, he suddenly notes palpitations, diaphoresis, dizziness, and a sense of overwhelming malaise. One minute later, he turned grey, lost consciousness, and collapsed onto the floor. An ECG revealed sustained monomorphic ventricular tachycardia at 150 bpm. Cardiopulmonary resuscitation was initiated and the patient was cardioverted to sinus rhythm with a 200-J biphasic shock delivered from an external defibrillator. The patient regained consciousness. There was no antecedent chest discomfort and cardiac enzymes were negative after the event. Serum electrolytes were also normal. He received an implantable cardioverter/defibrillator the next day.

Q

A 30-year-old woman presented to her general practitioner complaining of recurrent palpitations during exercise. She had previously been healthy and was on no medications. She described a long history of ‘skipped heart beats’. Her doctor arranged a treadmill exercise test, which demonstrated good effort tolerance and no evidence of ischaemia. During early recovery she developed sustained ventricular tachycardia with a left bundle branch block, inferior axis morphology. A cardiac MRI was performed that demonstrated normal biventricular function without evidence of myocardial scar or fatty infiltration. Electrophysiological testing was notable for inducible adenosine-sensitive ventricular tachycardia (with identical morphology to the clinical tachycardia) that was successfully ablated in the right ventricular outflow tract.

Q

A 42-year-old man complains of palpitations followed by dizziness and brief loss of consciousness. His wife reports that he is pale and short of breath. Emergency medical services were called and found him pulseless. The ECG revealed a rapid, irregular wide complex tachycardia. Later he was successfully resuscitated with two successive direct-current shocks.

Q

A 35-year-old man presents to an accident and emergency department with palpitations, shortness of breath, dizziness, and chest pain of 4 hours’ duration. An ECG demonstrated narrow-complex short RP tachycardia that responded to intravenous adenosine. The ECG during sinus rhythm revealed ventricular pre-excitation.
