Rhythm Irregularly: _____
Axis: ____
PR/P-wave: ____
QRS: ____
ST/T-wave: _____
QTc/other: ____
Diagnosis: ________

View Answers

Rate: 100 – one hundred fifty
Rhythm Irregularly: irregular
Axis: Normal
PR/P-wave: No p-wave was noticed. Fibrillating base range
QRS: Narrow
ST/T-wave: Normal
QTc/other: Normal

Diagnosis: This ECG shows atrial fibrillation (AF) with a new fast ventricular reply. With this historical past, the underlying medical diagnosis would fit together with a ‘holiday heart’ syndrome.

Q2. A 45 yr old businessman offers an experience that his center is racing. He or she has some lack of breath. This is certainly his ECG. Current your findings and offer a diagnosis.

Rate: ______
Rhythm Irregularly: _____
Axis: ____
PR/P-wave: ____
QRS: ____
QTc/other: ____
Diagnosis: ________

View Answers

Rate: 150
Rhythm Irregularly: Regular
Axis: Normal
PR/P-wave: No p-waves. Seesaw baseline
QRS: Narrow
QTc/other: Normal

Diagnosis: This is atrial flutter. Typically, the atria contract at 300 beats each minute causing a ‘seesaw’ baseline. Beats are transmitted with a 2: 1, 3: 1 or 4: 1 block, leading to ventricular rates of 150, 100 and 75 BPM respectively.

Q3. A 75-year-old man with a history of COPD presents with fever and increased sputum production. An ECG is taken in the emergency department. What does it show?

Rate: ______
Rhythm Irregularly: _____
Axis: ____
PR/P-wave: ____
QRS: ____
ST/T-wave: _____
QTc/other: ____
Diagnosis: ________

View Answers

Rate: 100 – one hundred fifty
Rhythm Irregularly: Irregularly irregular
Axis: Normal
PR/P-wave: Polymorphic p-waves (see arrows)
QRS: Narrow
ST/T-wave: Normal
QTc/other: Normal

Diagnosis: This will be polymorphic atrial tachycardia. It occurs within respiratory disease plus reflects an inept foci of atrial excitation. The morphology of the p-waves is therefore adjustable but all p-waves are transmitted with the bundle of Their and therefore the particular QRS complexes are usually all the exact same

Q4. A fit and well 31-year-old man presents for a routine insurance medical. This is his ECG. Present your findings and give the diagnosis.

Rate: ______
Rhythm Irregularly: _____
Axis: ____

Diagnosis: ________

Rate: 85
Rhythm Irregularly: Regular
Axis: Normal
PR/P-wave: Normal
QRS: Narrow
ST/T-wave: Normal
QTc/other: Normal

This is a normal ECG. There are many variants of normal and it is worth looking at as many ECGs as possible to get exposed to the common variants. It is crucial to remember that a very sick patient can have a normal ECG so always use all the information available to you and don’t rely on the ECG alone.

Q5. A 65-year-old man with a history of ischemic heart disease is found unresponsive. He has no central pulse and is making no respiratory effort. This is his ECG. What is the diagnosis and what will you do?

Rate: ______
Rhythm Irregularly: _____
Axis: ____
PR/P-wave: ____
QRS: ____
ST/T-wave: _____
QTc/other: ____
Diagnosis: ________

View Answers

Rate: 150
Rhythm: Regular
Axis:  Left axis deviation
PR/P-wave:  Not visible
QRS: Wide
ST/T-wave: Unable to assess
QTc/other: Unable to assess

This is ventricular tachycardia (VT) and in this case the patient is in cardiac arrest as they have no main pulse. He should be treated as per ALS guidelines with chest compressions beginning immediately. This is a shockable rhythm and should be treated using the ALS algorithm with DC cardioversion and adrenaline.

If typically, the patient was aware the ALS protocol will not be essential and management is determined by symptoms. If severely symptomatic urgent POWER cardioversion is suggested. When there were zero regarding decompensation (e. g. shortness regarding breath, chest soreness, shock, confusion, syncope) maybe he is managed pharmaceutically in the beginning.

Q6. A 72-year-old lady presents with collapse. This is her ECG. Present your findings. How would you proceed?

QTc/other:  Normal

Q8. A 55-year-old renal dialysis patient presents to the emergency department having missed his last session of dialysis due to feeling dizzy and unwell. This is his ECG. Present your findings and give a diagnosis.

Rate: 60
Rhythm: Normal
Axis: Normal
PR/P-wave: Shortened PR interval
QRS: Slurred’ upstroke on QRS
ST/T-wave: Normal
QTc/other: Normal

Diagnosis: This picture of shortened PR interval and slurred QRS upstroke – also known as a ‘delta wave’ – are typical of Wolff-Parkinson White (WPW) syndrome. These changes represent transmission through an accessory pathway. The history of collapse, in this case, is concerning as these episodes could be due to re-entrant tachycardias which can be fatal. Other features not seen here which may be present in WPW include a dominant R wave in V1 and T wave inversion in the anterior chest leads
