Describing an ECG




Sir, this is a 12 lead ECG of Mr. blah blah. It is correctly calibrated.

Heart rate is around 60/min, but there is a slight irregularity. P waves are normal and all p waves are followed by QRS complexes. Therefore, it is in sinus rhythm, and the irregularity is most likely to be due to sinus arrhythmia.

The cardiac axis is normal.

PR interval is normal.

There are small Q waves in inferior and lateral leads.

QRS complexes are normal and there is good R wave progression in anterior leads.

There are prominent ST elevations in leads II, III and aVF. There are also mild ST elevations in V5 and V6. There is ST segment depression in aVL.

T waves are upright and the QT interval appears to be normal.

In conclusion, this patient has an ACUTE INFERIOR ST ELEVATION MI with possible lateral extension and reciprocal ECG changes in lead aVL. There is sinus arrhythmia, but no evidence of AV nodal dysfunction. I would like to do V4R and V7-V9 to look for right ventricular and posterior involvement.

A 55 years old male patient admitted to medical casualty with a febrile illness for 3 days with myalgia. Examination was unremarkable. He was previously well except for chronic bilateral knee joint osteoarthritis. He consumed liquor quarter to half a bottle on a daily basis. Investigations revealed. WBC - 5.6 Hb - 11.2 Plt - 135 AST - 45 ALT - 42 S.Cr - 54 He was managed as viral fever and became fever free the next day. However the platelet count was persistently low around 130. Further investigations arranged. Blood picture - Thrombocytopenia probably due to liver disease S. Bilirubin, ALP - Normal S. Albumin - 38, S globulin - 37 USS abdomen - Coarse echogenicity of liver. Mild portal hypertension. Mild splenomegaly. Compatible with chronic liver cell disease. This patient has Cirrhosis with portal hypertension. Now the obvious cause for his cirrhosis is alcohol, isn't it? NO! Just because of the history of significant alcohol consumption you ca

A 32 years old previously healthy male patient admitted with a history of palpitations for 1 hour duration. He had experienced a similar episode a few months back which lasted only for few minutes. What are your concerns? First priority is to make sure that the patient is stable. Who is unstable? Hypotensive patient (Systolic BP < 90mmHg) Coronary ischemia (Ischemic chest pain) Cardiac failure (Patient has SOB) Patient with brain hypoperfusion (reduced conscious level) IF ANY OF ABOVE ARE PRESENT IRRESPECTIVE OF THE TYPE OF ARRHYTHMIA YOU WILL HAVE TO PERFORM DC CARDIOVERSION (SHOCK) ECG Analysing tachyarrhythmias is a long topic, which might bore you. Let's learn a few short cuts to diagnose common arrhythmias. Look at the QRS Is it narrow or broad? Narrow complex tachycardias we usually encounter are SVT (Read and understand the proper nomenclature. SVT is a wrong term!) Atrial fibrillation/ flutter In most patients both are managed the s
