#Micra Pacemaker

Meet the Micra by @medtronic —the world’s smallest pacemaker! 🩺✨ This tiny yet mighty device is used to treat slow heart rhythms (bradycardia) by delivering precise electrical pulses to help the heart beat regularly. What makes it revolutionary? 👉 It’s leadless—no wires required—reducing the risk of complications associated with traditional pacemakers. 👉 Its size and design make it a major advancement in pacing technology, offering a safer, less invasive option for patients. . . . . . #pacemaker #bradycardia #medtronic #medicaldevices #cardiologist

The Micra Leadless Pacemaker is a miniaturized, self-contained cardiac pacing system designed to eliminate the need for transvenous leads and a subcutaneous pocket. Implanted directly into the right ventricular endocardium via a femoral venous approach, it represents a major advancement in device-based rhythm management. 🔬 Design & Structure • Capsule-sized device (~25–30 mm, ~2 g) • Contains battery, electronics, and electrodes within a single unit • Fixation via nitinol tines that anchor to the RV myocardium ⚙️ Mechanism of Action • Provides VVI/VVIR pacing (ventricular demand pacing ± rate responsiveness) • Senses intrinsic ventricular activity and delivers pacing impulses when needed • Rate-responsive models adjust pacing based on patient activity 💡 Indications • Symptomatic bradycardia (e.g., sinus node dysfunction, AV block) • Patients unsuitable for transvenous systems (infection risk, limited venous access) • Elderly or frail patients requiring single-chamber pacing ⚡ Advantages • No leads → ↓ risk of lead fracture, dislodgement • No pocket → ↓ infection, hematoma • Cosmetically superior • Lower long-term complication rates ⚠️ Complications • Cardiac perforation, tamponade • Device dislodgement (rare) • Vascular access complications • Limited retrieval after endothelialization 🔋 Battery & Longevity • Approx. 10–12 years depending on pacing burden • End-of-life managed by implanting a new device alongside the old one 🩺 Clinical Significance The Micra system marks a paradigm shift in pacing by improving patient safety, reducing complications, and enhancing comfort—especially in high-risk populations. #Micra #LeadlessPacemaker #Cardiology #Electrophysiology #Bradycardia

✅️ A leadless pacemaker is a miniaturized, self-contained cardiac pacing device implanted directly into the right ventricle via a femoral venous catheter. Unlike traditional pacemakers, it has no leads and no surgical pocket, significantly reducing complications. 🔷 Key advantages: No leads → no lead fracture or infection No pocket → no pocket hematoma or erosion Lower infection risk overall Faster recovery and cosmetic benefit. 🔷 Limitations: Currently provides single-chamber ventricular pacing (VVI/VVIR) Not suitable for patients needing atrial pacing or CRT Battery replacement requires device retrieval or new implantation. 🔷 Best candidates: AF with slow ventricular response Patients with high infection risk Limited venous access Previous pacemaker infections 🔷 Common examples: Micra™ (Medtronic) Aveir™ (Abbott) ➡️ A major step toward simpler, safer pacing technology. #Cardiology #Pacemaker #LeadlessPacemaker #EPeeps #Electrophysiology #Arrhythmia #CardioInnovation #ECG #EKG #ECGPLUS1 #MEDICAL #

I often hear: “I’m so sorry you’ve had so many surgeries… that must be so tough.” But the truth is — I don’t know any different. This is my normal. And honestly? I feel incredibly lucky. Because how amazing is it that I get to live my life — raise my girls, chase my goals, and feel good — thanks to a device that literally keeps me alive every day. If you’re new to life with a pacemaker, I’m here to tell you: It’s not the end of your freedom — it’s the beginning of a new kind of strength. 💛 You’re safe here. And you’re not alone. Share this with someone you know who has a #pacemaker.

POV: you finally see what’s under the covers of a linac 👀

Whether it’s an external pacemaker for patients fresh out of cardiac surgery or an internally implanted device, all pacemakers have a universal code to understand their settings: The first letter tells you which chamber is paced The second letter tells you which chamber is sensed The third letter tells you what the pacemaker’s response to sensing will be Internal pacemakers have a fourth and fifth letter that describe rate response and multisite pacing Pacing means the device generates an electrical impulse to trigger a heart beat, this can happen in the atria (A), ventricle (V), or there can be DUAL pacing of both chambers (A+V) Sensing is the amount of electrical activity required for the pacemaker to “see” the patient’s native heart rhythm so the device can respond appropriately. Think of it like a fence. When we raise the sensitivity, we require a higher threshold of electrical activity in order for the pacemaker to “see” it. When we decrease the sensitivity, we lower the threshold of activity required to make it easier for the pacemaker to “see.” Response to Sensing is what the device will do with what it sees! -The pacemaker can have NO response to sensing (O), meaning it will fire at a consistent rate no matter what electrical activity it sees. We use this setting in some surgeries to prevent the pacemaker from inappropriately reading electrocautery artifact as a heartbeat. -It can inhibit (I) the pacemaker from firing after sensing a native heart beat to prevent inappropriate competition. This is commonly seen in external pacemakers after surgery. Devices are often set to AAI or VVI when we want to pace, sense, and then inhibit either from the atria or ventricle.
