1/ Let’s talk about focal atrial tachycardia #CardioTwitter.

đŸ§”đŸ‘‡ by @ekgdx

#ekgdx #ecg #ekg #MedTwitter #medicine #medstudents #basic #education #graphic Image
2/ Focal atrial tachycardia is characterized by at least three or more consecutive ectopic P waves with similar morphology, usually arising from a single ectopic focus.

#ekgdx
3/ Criteria

✅ ≄3 consecutive similar ectopic P waves (usually inverted in inferior leads).
✅ Atrial rate >100 bpm.
✅ QRS usually narrow unless pre-existing BBB or aberrant conduction.

AV dissociation, capture beats and fusion beats are all hallmarks of ventricular tachycardia

A simple understanding 👇

#CardioTwitter #Cardiology #Medtwitter
What’s a “capture beat” ?

During ventricular tachycardia, sometimes the SA nodal firing takes control of independent ventricular depolarization for brief moment, as this happens, “CAPTURE BEATS” appear. They are nothing but a brief moment of normal looking P-QRS pattern Image
Whats a “fusion beat” ?

During ventricular tachycardia, sometimes the SA nodal impulse and the independent ventricular impulse combine together to create a mix looking P-QRS pattern called fusion beats.

1/ Let’s talk about T waves #CardioTwitter

The T wave represents typically ventricular repolarization. It is the most labile wave on the EKG surface. 

Normal T wave

✅ Morphology: Asymmetric.
✅ Amplitude: ≀6 mm in limb leads and ≀10 mm in precordial leads.

#MedTwitter
2/ Tall upright T wave

Tall upright T waves are usually characterized by tall and peaked shape. 

✅ Amplitude: >6 mm in limb leads and >10 mm in precordial leads.

Causes: Hyperkalemia, hyperacute MI, normal variant, prinzmetal angina, aortic stenosis, LVH, RVH, others. 

#ecg
3/ Notched T wave

Possible causes: May be caused by morphological changes in the cardiomyocytes' action potential waveforms. Another causes include: Drugs (such as Dofetilide, Quinidine, Ranolazine, Verapamil), long QT syndrome, athletes, others.

1/ Let’s talk about the ST segment #CardioTwitter.

ST segment normally represents the interval between ventricular depolarization and repolarization.

Normal ST

✅ Usually isolectric or may vary from 0.5 mm below to 1 mm above isolectric line in L leads.

#ekgdx #Medicine Image
2/ ST elevation (STE)

ST changes suggesting myocardial injury:

✅ New STE ≄1 mm in all leads other than V2 or V3.
✅ New STE in V2-V3 ≄2 mm in men older than 40 years old and ≄2.5 mm in men younger than 40 years old or ≄1.5 mm in women.

#ekgdx #Medstudent #MedTwitter Image
3/ Types of ST segment elevation include:

✅ Convex Upward (previous pic)
✅ Horizontal (this one)
✅ Concave Upward (see next)
✅ Obliquely Straight (see next)

Three #cardiology cases with diagnostic ECGs in our resus room today and some learning points for emergency clinicians

#ecg #ekg
1. Sudden onset palpitations

ECG shows regular narrow complex tachycardia with rate around 140
We suspected this was atrial flutter
Rather than subject a patient to the horror of iv adenosine (which only reveals flutter - it can’t convert it), we moved the ECG limb leads around to get a ‘Lewis lead’ which better shows atrial activity

(See litfl.com/lewis-lead-s5-
 )

1/ Let’s talk about PR Interval - Segment #CardioTwitter.

The PR interval represents the time between the onset of atrial depolarization and the onset of ventricular depolarization and reflects conduction through the AV node.

đŸ§”by @ekgdx
2/ PR Interval

Criteria

✅ Normal PR interval: 0.12 - 0.20 sec.
✅ Prolonged PR interval: >0.20 sec.
✅ Short PR interval: <0.12 sec.

The term “PQ interval” is preferred by some EKG lover because it is the period actually measured unless the Q wave is absent.

#PR #interval
3/ The PR segment is the segment between the end of the P wave and the start of the QRS complex.

Criteria

✅ Normal PR segment: Usually isolectric.
✅ PR segment elevation: ≄0.5 mm.

PR segment elevation causes: Atrial ischaemia/infarction, myopericarditis, PE, others.

1/ Let’s talk about P waves #CardioTwitter.

The P wave is the first positive deflection on the EKG and represents atrial depolarization. The first half represents right atrial depolarization and the second half represents left atrial depolarization.

By @ekgdx Image
2/ Normal P wave

Criteria

✅ Axis: 0° to +75°.
✅ Amplitude (L leads): <2.5 mm.
✅ Amplitude (P leads): <1.5 mm.
✅ Duration: 0.08 - 0.11 sec. 
✅ Morphology: Upright in I, II, aVF and inverted in aVR.

#Pwaves #ecg #ekg #ekgdx #medicine #MedTwitter #MedStudentTwitter #basic
3/ Peaked P wave

The morphology is peaked with amplitude ≄2.5 mm, usually in II, III and aVF.

The peaked P wave is a typical characteristic of right atrial abnormality/enlargement. 

Causes: PE, COPD, congenital heart disease, pulmonary hypertension, normal variant, others. Image

Acute pulmonary embolism (PE) is one of the most serious form of venous thromboembolism. The clinical presentation of PE is variable and often nonspecific making the diagnosis challenging.

1/

#CardioTwitter Image
Criteria

✅ Sinus tachycardia (most common).
✅ S1Q3T3 pattern (may be present up to 30% of cases). 
✅ Simultaneous T wave inversions in the inferior leads and right precordial leads can be seen.
✅ Right axis deviation.
✅ RBBB (complete or incomplete).

Please retweet and share if you support my and others' vaccine injury recoveries. Image
My fiancé and I were supposed to get married in July 2022. Given the first 2 vaccine mandates, we figured that we had no choice but to keep on taking the boosters in order to be able to travel for our honeymoon / have liberties to go to stores etc.
We decided to take the 3rd @moderna_tx booster anticipating that perhaps it would also be mandated by the #Canadian #government.

Here’s the #ECG of a 68 year old man who was rushed to the ER by paramedics

BP: 80/40
HR: 150
RR: 35
SPO2: 95%

What’s the diagnosis?
Answer: HYPERKALEMIA

There’s a wide complex tachycardia with RBBB morphology. There are features here concerning for several life-threatening diagnoses including: V-Tach, Pulmonary Embolism, Acute Coronary Occlusion. But ALL these changes resolved with empiric ↑K+ treatment

The QRS width narrowed right before our eyes. His vital signs improved dramatically. This was the repeat ECG recorded just 20 minutes later. Lead V1 is artifact but otherwise you can see that all the extreme changes have now resolved, and only a hint of peaked T waves remain

#cardiotwitter #EPeeps #CardioEd #MedTwitter @TRassafMD @YoungDgk @DGK_org @YoungDZHK @AaronGoodman33 @Steph_Achenbach @fuzzymittens @AvrahamCooperMD Image
2/7 History
First described in 1953 by Osborn (camel-hump sign) upon #hypothermia in dogs. Upon systemic analysis similar #ECG patterns have been described in
âžĄïž hypercalcemia
âžĄïž brain injury
âžĄïž SAB
âžĄïž vasospastic angina / ischemia
3/7 Emslie-Smith et al showed that Osborn waves manifested more in epicardial than endocardial leads. Others finally showed that 4-aminopyridine sensitive transient outward current (Ito) is responsible and predominantly located in epicardium. âŹ‡ïž heart rate led to âŹ†ïž Ito current

My 1st symptoms of #COVID were 7 weeks ago tomorrow.

Yesterday I went for an #ECG b/c I'm having heart symptoms that weren't there before #COVID19.

I'm also having issues with my blood sugar which weren't there before #Covid_19

The technician said he's doing several ECG's ++
daily on people who are having heart complications due to #COVID19.

I'm on leave from my job. And now I'm in need of health care I wasn't before. I'm scared of what is happening inside my body and brain.

@TimHoustonNS got rid of all the means that protected the #NovaScotia ++
population. Our health care and workers are crumbling under the weight of it all.

Businesses are closing. Housing is a mess. The climate is in shambles.

What are we going to do?
