Have you ever wondered why our monitors are so accurate and how we differ from current competitors on the market? 🛑 Older Hemodynamic Monitors: ▪ Single beat analysis ▪ CO= PP x HR 🚫 PP increases due to SV increase, but also due to vasopressors. These algorithms cannot tell them apart. 💪 Argos Hemodynamic Monitor ▪ Multi-Beat Analysis ▪ CO= (MAP-CV)/SVR ✅ Accuracy is not impacted by arrythmia, changes in vasomotor tone, or low CO *Other hemodynamic monitors analyze one beat at a time and assume that cardiac output is proportional to pulse pressure X heart rate. This assumption has a fundamental flaw. As you know, pulse pressure will increase when you give fluids to a fluid responder, just like stroke volume. Pulse pressure will also increase if you give a vasopressor due to pulse pressure amplification. So, any monitor that assumes that Cardiac output is proportional to PP x HR can’t tell the difference between increases in stroke volume and increases in SVR. This is why the literature shows that other pulse contour technologies fail during changes in vasomotor tone.    What we do is analyze 20 seconds of heart beats and create a model of the circulation, including the vascular resistance and other parameters. Then we vary the parameters until the model waveform matches the observed waveform. Once the waveforms match, then we know the resistance and we get cardiac output by taking (MAP - CVP) and dividing it by SVR. Since we model the resistance directly, our algorithm is not adversely impacted by vasomotor tone changes. Plus, because we use multiple heat beats to determine the cardiac output, our algorithm also works during arrhythmia, whereas the others do not. 

ECG Case Study #4: Why Are QRS Complexes Occurring in Pairs? 🩺 Today, we’re looking at an ECG tracing where QRS complexes appear in pairs. Understanding why this pairing occurs provides key insights into underlying cardiac rhythm disturbances. Take a look at the options below and share your diagnosis! Question: Why do the QRS complexes occur in pairs? Options: A. Atrial Bigeminy   B. Junctional Bigeminy   C. Ventricular Bigeminy   D. Atrial Flutter with Alternating Atrioventricular (AV) Conduction Ratio (2:1 alternating with 4:1) Considerations for Interpretation:   1️⃣ Bigeminy is a rhythm pattern where each normal beat is followed by a premature beat, resulting in paired QRS complexes. The location of the premature beat (atrial, junctional, or ventricular) will affect QRS morphology and PR intervals.   2️⃣ Atrial Flutter with Alternating AV Conduction: Atrial flutter may present as a paired QRS pattern if there’s a changing conduction ratio. When AV conduction alternates, such as a 2:1 followed by a 4:1 conduction ratio, QRS complexes can appear in pairs on the tracing. How to Differentiate:   - Examine P waves: Identify if there’s a flutter wave (sawtooth pattern) or premature atrial beat. - QRS Morphology: If the premature beats are ventricular, the QRS complexes will appear wider. - PR Interval: Check for variations in PR intervals to distinguish between atrial and junctional bigeminy.

POSTCOVID-19 WAR era, Overestimation of certain medical tools after COVID-19 pandemic attacks clearly have established that none of so-called ICT- and AI-related modern tools were good enough to assess an appropriate prognostics, diagnostics and remain supportive tool for certain longcovid-patients Medicare and Medicaid, since 2019. All kinds of Medical (imaging) tools failed to help appropriate diagnostics during COVID-19 pandemic attacks, especially in CAD and Cancer patients, which resulted in an excessive increase in morbidity and mortality rates, significantly. More than 7 up to 30 million died in less than 4 years, and counting (Bahram Alamdary Badlou et al. 2020-2024 different publications).

Cardiac computed tomography (CT) encompasses techniques like coronary CT angiography (CCTA) to visualize coronary arteries, cardiac calcium scoring for plaque assessment, and functional assessments for heart performance. CCTA aids in diagnosing coronary artery disease by detecting blockages or narrowing. Cardiac calcium scoring estimates cardiovascular risk by measuring calcified plaque. Functional assessments evaluate blood flow and coronary artery lesions. Despite benefits like detailed insights into heart health, CT involves radiation exposure and may not be suitable for all patients. Nonetheless, it remains a crucial tool for diagnosing and managing cardiovascular conditions.

🔍 Understanding the Heart from the Inside: The Significance of Cardiac MRI 💓 Cardiac MRI is a game-changer in cardiac diagnostics, providing unparalleled insight into heart structure and function. By using advanced imaging techniques, it delivers detailed, high-resolution images that help in the early detection and precise evaluation of heart conditions such as cardiomyopathy, congenital heart disease, and myocardial infarction. Why it matters: ✅ Accurate Diagnosis: Pinpoints abnormalities that other imaging techniques might miss. ✅ Non-Invasive: Safe and painless with no exposure to ionizing radiation. ✅ Comprehensive Assessment: Evaluates heart muscle, valves, and blood vessels in one scan. Harnessing the power of cardiac MRI enables timely and targeted treatment, improving patient outcomes and paving the way for a healthier future. 🌟 #CardiacMRI #HealthcareInnovation #MedicalImaging #HeartHealth

Meet Willy - Your Guide to the Circle of Willis and TCD Ultrasound! Willy, inspired by the Circle of Willis, embodies the critical role TCD ultrasound plays in modern stroke care. The Circle of Willis supplies up to 80% of the blood to the brain and is the most important source of collateral circulation. When an artery becomes blocked or damaged due to significant extracranial disease like stenosis, hemorrhage, or stroke, collateral circulation provides alternative routes for blood flow. TCD is the only non-invasive method for continuous, real-time monitoring of blood flowing through this important structure. TCD can detect emboli, the narrowing of blood vessels, vasospasm due to hemorrhage, and much more. Due to the unique and important information provided by TCD, it is a required technology for all comprehensive stroke centers. Learn more: www.neurasignal.com

This is awesome new technology - using 3d cardiac #MRI and Gadolinium enhancement to identify slow re-entry conduction pathways in repaired #Fallots tetralogy

Echocardiography of a four-year-old cat with ascites revealed a large, occlusive thrombus in the right pulmonary artery. The initial examination showed right heart enlargement, spontaneous contrast in the right atrium, and the presence of a thrombus in the right pulmonary artery. Subsequent ultrasound images after ten days indicated successful thrombolysis, with complete resolution of the initial cardiac modifications.

🚩Case of the week🧨 Hypertensive heart disease or hypertrophic cardiomyopathy? A 52-year-old male pilot was referred by his cardiologist for a cardiac MRI. He has a history of hypertension and is currently on ARB and beta-blocker. He presented with a new left bundle branch block. On echo, there was a hypertrophy up to 17 mm without obstruction. The MRI was performed after discontinuation of the beta-blocker and showed: Septal hypertrophy of 17 mm in the basal and mid segments, Subaortic obstruction with SAM and MR, Slightly elevated T1 of 1020 ms in the septum; discrete enhancement of the LV/RV junctions. While the MRI findings alone were not specific enough to formally conclude, the overall presentation is suggestive of hypertrophic cardiomyopathy.

Abstract In the 2000s, cardiac resynchronization therapy (CRT) became a revolutionary treatment of heart failure with reduced left ventricular ejection fraction (HFrEF) and wide QRS. However, about one-third of CRT recipients do not show a favorable response. This review of the current literature aims to better define the concept of CRT response/nonresponse. The diagnosis of CRT nonresponder should be viewed as a continuum, and it cannot rely solely on a single parameter. Moreover, baseline features of some patients might predict an unfavorable response. A strong collaboration between heart failure specialists and electrophysiologists is key to overcoming this challenge with multiple strategies. In the contemporary era, new pacing modalities, such as His-bundle pacing and left bundle branch area pacing, represent a promising alternative to CRT. Observational studies have demonstrated their potential; however, several limitations should be addressed. Large randomized controlled trials are needed to prove their efficacy in HFrEF with electromechanical dyssynchrony.
