What is the link between thyroid and heart disease?
Heart disease can occur with both increased function of the thyroid gland and decreased function of the thyroid gland. When thyroid function is increased, heart rate increases and the work load of the heart increases.
In severe cases heart failure may occur. A peculiarity of heart failure associated with increased thyroid function is that it is a high output failure unlike the usual heart failure in which the pumping function of the heart is reduced, and low output failure occurs.
While in low output heart failure the extremities are cold, in high output failure due to increased thyroid function, the extremities of the lim...

Relation Between Stroke and Heart Disease
Stroke is often due to sudden loss of blood supply to a region of the brain which usually results in paralysis of a part of the body. Stroke could also be due to bleeding into a part of the brain.
Strokes and heart disease are linked together in various ways. In general, risk factors for stroke and some forms of heart disease are similar. Strokes due to blocks in blood vessels, can be seen along with blocks in blood vessels of the heart.
Stroke can occur after a heart attack as well. Heart attack damages a part of the heart muscle. This can lead to damage of the inner lining of the heart in that region. A blood clot can fo...

Potential Risk of Serious Bleeding in Patients With AF Using Diltiazem With Apixaban or Rivaroxaban
A potentially serious drug interaction between diltiazem and apixaban or rivaroxaban has been reported in US Medicare patients taking these drugs together for atrial fibrillation. The study has been published as online ahead of print in the Journal of American Medical Asociation [1]. The study compared serious bleeding risk for new users of apixaban or rivaroxaban with atrial fibrillation treated with diltiazem or metoprolol. It was a retrospective cohort study which included US Medicare benefiaries aged 65 years or more with atrial fibrillation and follow up period was one year. Primary outcome was a composite of bleedi...

From Patent To Product: The Speed Of The Digital Health Evolution
We’re bombarded with mindblowing headlines of new medical miracles every day. BCI helps paralysed patients talk again! Robots in the stomach! Micro-organs on organ-on-chip technologies! But it is almost impossible to see through the hype and know if and when these will yield actual, patient-ready solutions. So let’s get into this maze and decipher how a new, revolutionary medical technology develops from an ingenious idea to a market-ready product with two real-life examples: the artificial pancreas and wireless ECG.
In early April, the UK’s NHS rolled out an artificial pancreas (APS) for Type 1 diabetes patients,...

Assessment of LV Diastolic Function by Echo in SR and AF
Echocardiographic assessment of left ventricular diastolic function with special reference on diastolic function assessment in atrial fibrillation.
Though there are several parameters for evaluation of left ventricular diastolic function by echocardiography, the most commonly used are the pulsed Doppler mitral E/A ratio and tissue Doppler mitral E/e’ ratio.
Some of the other useful parameters are mitral E velocity deceleration time, changes in mitral inflow with Valsalva maneuver, mitral L velocity, isovolumic relaxation time, left atrial maximum volume index, pulmonary vein systolic/diastolic velocity ratio, color M-mod...

Ashman Phenomenon in A F and Fish Criteria
Transcript of the video: Now I am going to describe Ashman Phenomenon in atrial fibrillation, which is responsible for a long and short sequence followed by a wide QRS, in atrial fibrillation noted on ECG, which may resemble a ventricular ectopic beat.
This is the diagrammatic representation of Ashman phenomenon. You have sequences of AF beats, and a long cycle occurs, followed by a short cycle. So this QRS is aberrant, having rSR’ pattern, resembling right bundle branch block pattern. This was described by Richard Ashman, from Lousiana State University School of Medicine in New Orleans. This is the long cycle. Durin...

Ventricular Fibrillation, ICD, LBBB, QRS of 210 ms, Positive Smith Modified Sgarbossa Criteria, and Pacemaker-Mediated Tachycardia
An elderly man collapsed. There was no bystander CPR. Medics found him in ventricular fibrillation. He was defibrillated, but they also noticed that he was being internally defibrillated and then found that he had an implantable ICD.He was unidentified and there were no records availableAfter 7 shocks, he was successfully defibrillated and brought to the ED.Bedside ED ultrasound showed exceedingly poor global LV function, and no B lines.Here is the initial ED ECG. What do you think?Rhythm: Residents asked me why it is not VT. If you use calipers (or equvalent), it is clear that the rhythm...

Brugada Syndrome
Transcript of the video: Brugada Syndrome was described by Brugada brothers in 1992 as right bundle branch block pattern in anterior leads with ST segment elevation and syncope or sudden cardiac death and it was later in 1998, that the genetic basis of the disease was identified, with mutations in sodium channel. Later on, several other mutations have been attributed to cause the ECG pattern in Brugada syndrome.
I am always happy to see this ECG of Brugada syndrome sent to me by Professor Josep Brugada, in 2001, for the inaugural issue of the Indian Pacing and Electrophysiology Journal, which I started in 2001. And, this r...

Wide Complex Tachycardia -- VT, SVT, or A Fib with RVR? If SVT, is it AVNRT or AVRT?
A 69 y.o. male with pertinent past medical history including Atrial fibrillation, atrial flutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Per EMS report, patient believes he has been in atrial fibrillation for 5 days, since coming down with flu-like illness with rhinorrhea, productive cough, SOB. Patient is on rivaroxaben, carvedilol, and dofetilide (to suppress atrial fib -- rhythm control). He states that he maybe missed a dose or two during recent illness. On EMS arrival, patient ' s oxygen sat...

Pediatric Exercise Testing
Discussion on pediatric exercise testing.
Pediatric exercise testing may be used for evaluation of various disorders of cardiac rhythm rather than for inducible ischemia as in adults.
In a child with suspected sinus node dysfunction, chronotropic incompetence from sinus node dysfunction can be assessed by exercise testing.
Evaluation of escape rates and ventricular ectopy with exercise in complete heart block is an important aspect in the evaluation of congenital complete heart block.
ECG showing congenital complete heart block with ventricular rate of 47/min and atrial rate of 63/min.
In stage I of Bruce protocol, the atr...

Palpitations and presyncope in a 40-something
Discussion: Putting all of the information together this patient is most likely suffering from arrhythmogenic cardiomyopathy (AC) better known as ARVC. The medical hx is typical, with sudden onset tachydysrhythmia during physical exertion. It is not uncommon for the initial presentation to be sudden cardiac death (SCD). In fact it is one of the leading causes of SCD in people age less than 40 years. Thus it is very important to identify this disorder. AC is a disease in which myocardium is replaced by fibrofatty tissue. This usually and predominantly affects the RV free wall and apical regions, but it can affect the left v...

A young man presented with a gunshot wound to the right chest, with hemo-pneumothorax and hemorrhagic shock.He got a chest tube and intubation and massive transfusion and stabilized.CT of chest showed the bullet path through his right lung but nowhere near his heart.But he did get an EKG:What is this? There were times when it would be usurped by sinus tachycardia, then return to this rhythm.There is a wide complex. It is irregular. It is not fast (cannot be VT).
