1/ What better way to end off a week of pacemakers and ICDs than recapping and revisiting our #12LeadThursday series!

🧵 Image
2/ Which patients get pacemakers?

Think of 2 big buckets: conduction disease and heart failure Image
3/ Let’s start with conduction disease!

Refresh your memory with this past byte - 80 y/o M with hx of CABG…what's the rhythm?
bit.ly/40cAry0
4/ One way to think about Class I indications for pacemakers is by their relation to the AV node Image
5/ Now onto heart failure!

Remember this byte?! 60 y/o M with symptomatic heart failure on guideline-directed medical therapy comes into your office…
bit.ly/3o7vfOz Image
6/ There’s three indications for CRT! Test your knowledge with this slide Image
7/ Let’s review! What are the PPM indications for dual chamber pacemakers?

What about BiV pacemakers? Image
8/ Where are the leads located for single chamber, dual chamber, and BiV pacemakers?! Image
9/ You can use EKGs to determine where leads are located!

Remember this byte?! New patients being admitted for heart failure…
bit.ly/3UwyT0i Image
10/ Use this graphic to review how lead placements will show up on an EKG!

For example, if the lead is in the RV apex, the EKG will result in a LBBB-like morphology Image
11/ What does the following look like ECG?
- V-paced
- A-paced
- A-sensed and V-paced
- A-paced and V-paced Image
12/ What about monitoring?

Remember this byte? Your patient presents for routine follow up in cardiology clinic! What’s the rhythm?
bit.ly/3KWgS8H Image
13/ Atrial activity should be assessed in all patients! Regardless of the presence of a pacemaker.

If they have an atrial arrhythmia, remember to evaluate for anticoagulation! Image
14/ What a packed week of pacemakers! Let’s review what we talked about:

- Pacemakers indications
- Using EKGs to determine lead location and sensing
- Monitoring patients with pacemakers Image
15/ Check out our latest podcast on all things pacemakers and ICDs for more information! Shoutout to @SamuelMaidman and Vorada Sakulsaengprapha for this awesome byte!

1/ 🚨 NEW #5Pearls on HFpEF!

HFpEF is:
- Clinical syndrome of heart failure w/ EF 50%+
- ☂️ term | Heterogeneous disease 

HFpEF is NOT:
- Classic high BP, causing stiff ventricles

2/ Clinically, HFpEF is:

🫀Dyspnea on exertion
🫀PND
🫀Orthopnea
🫀Fatigue
🫀Exercise intolerance
🫀JVD
🫀Pulmonary rales
🫀LE edema
3/ On echo, HFpEF is NOT:
🫀Just diastolic dysfunction

**Diastolic dysfunction CAN be seen in HFpEF 

But, it was not observed on resting echocardiograms of ⅓ of HFpEF patients in the Paragon-HF trial ‼️

1/ 🚨 NEW #5Pearls episode on Cardiorenal Considerations 🫀🫘

So many diuretic options, so which to choose and why?

Use the toolkit ⤵️ for all your diuresis needs!

2/ Not all AKI in heart failure is cardiorenal syndrome!

In pure cardiorenal, expect a “bland” UA with no:
🥩 Protein
🩸 Blood
🦠 Granular or other cell casts!

**Remember, keep a broad differential for AKI
3/ You suspect volume overload in a patient…what dose of diuretic do you start with?

2.5x their home dose of diuretic (in IV form)!

IV options include:
💉 Furosemide
💉 Bumetanide

**Bumetanide drip at higher doses is associated with myalgias

1/ Time for #12LeadThursday!

What’s the axis and do you notice anything about the precordial leads? Image
2/ What do you see on ECG to identify extreme axis deviation?

Negative deflection in lead I + negative deflection in aVF = extreme axis deviation Image
3/ What about the precordial leads?

Do you notice dominant R waves, S waves, or T-wave inversions? Image

1/ Atrial Fibrillation: #GrayMatters Series

What do you do with that episode of #Afib when sick or post-op in the hospital?

What type of monitoring is best?

2/ When do you start AC for new Afib post-op?

We hope this infographic will be handy for the many times we may be in the gray zone!

From @accpchest guidelines

A few things to consider:
🤔 Patient specific risk
🤔 Blood thinner of choice
🤔 Bleeding risk of the surgery
3/ Credit to the team that worked tirelessly on this!

1/🚨New Episode🚨
The Lipid Panel Reimagined: #MindtheGap Segment

How do you interpret the #lipidpanel to help inform patients' risk for #cardiovascular disease? Do you use #ApoB? 🧐

🎧: link.chtbl.com/Lipids
Sponsor: go.amboss.com/CoreIM-E8
2/ Unfortunately, our patient is stuck in "bumper-to-bumper" #cholesterol traffic 🚗!

See traffic analogy to understand why ApoB can give us information that LDL-C may not:

#Mindblown! 🤯
3/ Overall, LOWER ⬇️ is better for both #LDL-C and #ApoB in terms of reducing #CV disease risk!

But #discordance between LDL-C vs. ApoB is actually quite common!

Take a look at the orange line to see how ApoB confers a higher CVD risk over time 👇

1/ November 14th is #WorldDiabetesDay

Let’s look back at one of the most influential #RCTs for

how we given insulin in #T2DM?

the #RABBIT2 trial🐰🧵

#Insulin #MedTwitter
2/ The #RABBIT2 study looked at the (1) efficacy and (2) safety of basal-bolus vs. sliding-scale #insulin in non-critical inpatients🏥.

Basal-bolus regimens consisted of a combo of #Glargine (basal) and #Glulisine (mealtime).

The primary outcome was average glucose🍬.
3/ See below for a graphical depiction of how the study was performed👇:
