The SA node initiates the electrical event that normally causes the heartbeat . The ability of certain myocardial cells to spontaneously discharge electrically (action potential) without the need for external stimulus is called automaticity. The heart is unique in this property. . . All other muscles in the body require stimulation from nerve impulses supplied by the nervous system. If nerves supplying the voluntary muscles are cut, these muscles cease to function; in other words, they are paralyzed. . . In contrast, if the nerves supplying the heart are severed, the heart will continue to beat. The cells that possess the property of automaticity are called pacemaker cells. The SA node serves as the heart’s primary pacemaker and has an intrinsic (natural) rate of 60 to 100 beats per minute. . . Thank you for sharing @ekg_master . .

Impella is a heart support device that can be inserted either percutaneously or surgically. It works by drawing blood from the ventricle and expelling it into the aorta, which reduces left ventricular end diastolic pressures, myocardial oxygen demand, and pulmonary capillary wedge pressure (PCWP), while increasing cardiac output and mean arterial pressure (MAP). This eases the heart’s workload, which helps with ventricular recovery. Types 👀 Impella is available in various models tailored to our patient’s specific needs. Most are designed for insertion into the left ventricle to support left ventricular function, but some can be inserted into the RV for right ventricular support (Impella RP). The Impella 5.5 (which is shown in the graphic) is specifically designed to pull blood from the left ventricle and expel it into the ascending aorta. You can even have Bipella where you have one impella in the LV and one in the RV! Indications ✅ Impella devices are used for ventricular recovery: 1️⃣ Cardiogenic Shock 2️⃣ Bridge to Transplant 3️⃣ High-Risk PCI 4️⃣ Fulminant Myocarditis 5️⃣ Extra conditions: peripartum/postpartum induced heart failure, various forms of cardiomyopathy. Monitoring and Support 🖥️ Impellas often require monitoring such as the use of a pulmonary artery (PA) catheter/Arterial line, alongside frequent echos/bedside point of care ultrasound (POCUS) to assess heart function/device placement. Management of these patients requires frequent hemodynamic monitoring such as cardiac output (CO), systemic vascular resistance (SVR), and pulmonary artery pulsatility index (PAPI). Another useful measure of cardiac function is using the FICK equation. #FOAMed #nurse #paramedic #ems #emt #medical #meded #medicaleducation #criticalcare #flightnurse #criticalcaremedicine #criticalcaretransport #nursing #emergencynursing #intensivecare #medicine #flightparamedic #ambulance #physician #physicianassistant #PANCE #PANCEprep #nremt #CVICU #impella #cardiology

Imaging a beating heart...⁣ ⁣ ⁣Repost from @theradiologistpage🔻 ⁣ CARDIAC MRI FOUR CHAMBER VIEW⁣ 👨🏽💻Here we have a ‘4 chamber view’ of a cardiac MRI - this ‘cine’ image gives us a view of the right and left atria and both ventricles, hence the term ‘four chamber’⁣ ⁣ 👨🏽💻We can identify the left ventricle by its thick wall - on this image we can assess the septal and lateral walls as well as the apex. We can look to see if there is any poor movement of the LV wall which may be induced by iscahemia - we are checking to see all of the LV wall contracts in sync. If one part of the wall does not move it can give a clue that there is a stenosis within one of the coronary arteries, for example a hypokinetic lateral wall may be a sign of left circumflex disease and a poorly moving LV septum can be a sign of left anterior descending artery disease ⁣ ⁣ 👨🏽💻We can also check the right ventricle which is the most anterior heart chamber. Check out the ‘moderator band’ - a muscular band of fibrous tissue that attaches at the septum and which tells us this is the right ventricle (especially helpful in congenital heart disease where the ventricles can be difficult to classify)⁣ ⁣ 👨🏽💻As well as commenting on chamber size, this view also gives us a nice view of the mitral and tricuspid valves - we can say if there is any stenosis or whether there is a jet of blood coming back into the atrium suggesting regurgitation ⁣ ⁣ ———⁣ #MedEd #medicalstudent #medicine #FOAMed #cardiology #heart #rhythm #medical #ecg #ecginterpretation #nurse #nurses #studentnurse #cardiacnurse #cathlab #ekgtechnician #ekg #learn #education #medstudent #aprn #physicianassistant #cardiology #cardiologyfellow

The Cardiac Cycle with EKG Insights Our hearts beat relentlessly, but have you ever wondered what goes on inside this incredible organ? 🤔 Join me on a journey through the phases of the cardiac cycle, and let's dive into the world of EKG (Electrocardiogram) to gain deeper insights into its rhythms! 🚀 1️⃣ Atrial Contraction (Atrial Systole): The cycle begins with the atria contracting, pushing blood into the ventricles. This phase is represented by the P-wave on the EKG, marking the depolarization of the atria. 💥💘 2️⃣ Ventricular Contraction (Ventricular Systole): Next, the ventricles contract, forcing blood into the pulmonary artery and aorta. This is when the QRS complex on the EKG occurs, signifying ventricular depolarization. 🎵💪 3️⃣ Isovolumetric Relaxation: After the ventricles empty, they briefly relax, but all valves remain closed. The EKG remains flat during this momentary pause, reflecting electrical quiescence. 🛑🕒 4️⃣ Atrial Filling (Atrial Diastole): As the ventricles relax, the atria fill with blood from the veins. The EKG continues to show electrical calmness. 🔄❤️ 5️⃣ Ventricular Filling (Ventricular Diastole): The final phase sees the ventricles passively filling with blood from the atria, preparing for the next contraction. This is often represented by the T-wave on the EKG, signifying ventricular repolarization. ⏳🌊 Understanding these phases, coupled with insights from the EKG, helps us appreciate the intricate dance of the heart's electrical and mechanical activities that keep life flowing. 🩺🌟 . . .

⚠️ The impella heart pump is a device that offers ventricular support. ✅ This impella CP is placed across the aortic valve and into the left ventricle. The nice thing about this device is that it assists in direct left ventricular unloading and aids in forward flow. ✅ The impella CP in this clip pulls blood through the inlet (inside the LV) and transports it out through the outlet (in the aortic root). ✅ The impella RP is placed via the venous route (femoral vein in this clip) with the inlet sitting in the IVC and outlet in the main pulmonary artery. ✅This can be a very effective method in providing biventricular support. ✅ Typically this device will be used for high risk percutaneous coronary intervention, cardiogenic shock, and decompensated heart failure. . . . #medstudent #Cardiology #cardiologist #physicianassistant #Aprn #cardiologyfellow #cardiologist #medical #nurse #nursingstudent
