Coarse atrial fibrillation on ECG Atrial fibrillation is recognized on ECG by the absence of P waves and presence of fibrillary waves. Sometimes fibrillary waves may be quite fine so as to be almost unrecognizable in certain leads. In such cases, absence of P waves and a totally irregular RR interval will give the clue to the presence of underlying atrial fibrillation. It may be difficult to recognize the irregularity of RR interval when the ventricular rate is fast, especially in a short ECG strip. Looking at a long rhythm strip and close scrutiny of RR intervals to locate 50% variation between the longest and shortest R...

CONCLUSIONS: Based on experience with patients, the Trifecta GT demonstrated an excellent hemodynamic performance after implantation, which involved a simple and safe technique. Further long-term studies to determine the durability of the prosthesis are required. PMID: 30207124 [PubMed - in process]

If you delivered a baby early, you may want to pay closer attention to your heart health. A study published in the journal Hypertension shows that a history of preterm birth (defined as a birth before the 37th week of pregnancy) may bring health risks for not only for baby, but for mom, too. The study found that women who delivered a baby preterm were more likely to experience rising blood pressures later, compared to women who delivered closer to term. If they had this pattern, they were also more likely to show signs of coronary artery disease, which is associated with an increased risk of heart attack and stroke. Becaus...

The test takes 15mins and can be performed by a GP, with results available to patients within three days - so they no longer face an agonising wait to be referred to a specialist clinic for scans.

ConclusionThe feasibility of the PET-CMRA framework for simultaneous cardiac PET-MR imaging in a short and predictable scan time (~11  min) has been demonstrated in 14 patients with CTO. Motion correction increased visible length and sharpness of the coronary arteries by CMRA, and improved delineation of the myocardium by18F-FDG PET, resulting in good agreement with X-ray angiography and LGE-MRI.

(University of Edinburgh) Heart scans for patients with chest pains could save thousands of lives, research led by the University of Edinburgh suggests. The life-saving scans -- called CT angiograms -- helped to spot those with heart disease so they could be given treatments to prevent heart attacks. Researchers say current guidelines should be updated to incorporate the scans into routine care.

American physicians dole out lots of unnecessary medical care to their patients. They prescribe things like antibiotics for people with viral infections, order expensive CT scans for patients with transitory back pain, and obtain screening EKGs for people with no signs or symptoms of heart disease. Some critics even accuse physicians of ordering such services to bolster their revenue. So what happens when uninsured patients make it to the doctor’s office with coughs, low back pain, or other problems? Do physicians stop ordering all these unnecessary tests and services, out of recognition that most of these patients w...

By MATTHEW HOLT Happy 15th birthday THCB! Yes, 15 years ago today this little blog opened for business and changed my life (and at least impacted a few others). Later this week we are going to celebrate and tell you a bit more about what the next 15 years (really?) of THCB might look like. But for now, I’m rerunning a few of my favorite pieces from the mid-2000s, the golden age of blogging. Today I present “Health Care = Communism + Frappuccinos”, one of my favorites about the relationship between government and private sector originally published here on Jan7, 2005. And like the Medicare one from last we...
