Clinical Examination of Cardiovascular System For Medical Students
Discussion on blood pressure is not included here as a separate topic is dedicated to it.
Though the most commonly examined pulse is the radial, to check some of the characteristics, a more proximal pulse like the brachial or carotid needs to be examined. Following parameters of the pulse are routinely documented: 1. The rate: Normal rate in adult is 60-100 per minute. It is higher in children. Younger the child, higher the pulse rate.
Rhythm: Regular and irregular rhythms are possible. Mild variation with respiration is called respiratory sinus arrhythmia, with higher rate in inspiration. Respiratory sinus arrhythmia may...

In this study, we used a Drosophila model to understand the role of the dec2P384R mutation on animal health and elucidate the mechanisms driving these physiological changes. We found that the expression of the mammalian dec2P384R transgene in fly sleep neurons was sufficient to mimic the short sleep phenotype observed in mammals. Remarkably, dec2P384Rmutants lived significantly longer with improved health despite sleeping less. In particular, dec2P384R mutants were more stress resistant and displayed improved mitochondrial fitness in flight muscles. Differential gene expression analyses went on to reveal several altered tr...

20-something with huge verapamil overdose and cardiogenic shock
A 20-something presented after a huge verapamil overdose in cardiogenic shock. He had been seen at an outside institution and been given 6 g calcium gluconate, KCl, and a norepinephrine drip.The initial K was 3.0 mEq/L and ionized calcium was 5.5 mg/dL (sorry, Europeans, for the weird units)Here was the initial ED ECG:There is a junctional rhythm with retrograde P-waves (see the dip in the T-wave in lead II across the bottom; you can follow that up to all the other leads and see the retrograde P wave). There is also Left Bundle Branch Block (LBBB). There is huge proportionally excessively discord...

Can You Take Birth Control Pills With Hypertension?
Navigating birth control options when living with hypertension can be challenging. This comprehensive overview explores the complex relationship between birth control pills and high blood pressure, addressing scientific research, potential risks, and viable alternatives. It underscores the importance of personalized medical advice in making safe and informed contraceptive choices.
Quick Summary
Combined oral contraceptives can potentially raise blood pressure levels, making them a risk for women already diagnosed with hypertension.
Alternatives such as progestin-only pills, IUDs, barrier methods, and contrace...

12 Ways To Effectively Prevent High Blood Pressure
Conclusion
In a nutshell, preventing high blood pressure is undeniably easier and effective than treating it. The increasing prevalence and devastating consequences of this condition necessitate proactive measures.
By adopting a healthy lifestyle, making mindful dietary choices, engaging in regular exercise, managing stress, and prioritizing sleep, we can effectively prevent high blood pressure and its complications.
Regular check-ups, limiting caffeine and sodium intake, managing chronic conditions, practicing mindful eating, and avoiding processed foods are additional steps to consider.
While an organic...
