EKG Rhythm Strips Practice Pre Test 2024
Q1. A thirty-five-year-old person presents with tremors. He’s been ingesting heavily with close friends this past weekend. This is usually his ECG. Current your findings in addition to give a medical diagnosis.
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.
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: 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.
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: 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?
Q7. A 62-year-old person presents with restricted core chest soreness radiating to his / her left shoulder. This specific is his first ECG. Present your current findings and offer an analysis.
Rate: 90 Rhythm Regular Axis:Normal PR/P-wave:Normal QRS: Narrow ST/T-wave:Grossly elevated inside V2, V3, V4, V5 and V-6. Reciprocal depression inside II, III in addition to aVF. 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: 100 -150 Rhythm: Irregular Axis: Unable to establish PR/P-wave:Not visible QRS: Widened ST/T-wave:Merged with QRS QTc/other:Unable to assess
Q9. A 65-year-old woman presents with chest pain radiating to her jaw and down her left arm. It feels like her ‘normal’ angina nevertheless at this juncture it provides not eased together with GTN spray. This specific is her ECG. Present your conclusions and give typically the diagnosis.
Rate: 60 Rhythm: Normal Axis: Normal PR/P-wave:Normal QRS: Normal ST/T-wave:T trend inverted in 2 III and aVF, V4 – V5. ST elevation inside aVR> 1mm QTc/other:Normal
Q10. A 25-year-old man offers with a failure which occurred when he was playing in a football match. He’s suffered episodes of fainting in typically the past. This is certainly his / her ECG. Is it usually a medical 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
