Tilted ECG - An unusual tilt test response

Indian Pacing and Electrophysiology Journal, 2017
Tilt testing is a commonly used diagnostic tool to evaluate syncope of undetermined etiology. We hereby describe a twelve year old male child who developed presyncope during provocative head up tilt testing along with ST segment elevation in cardiac ...

Inflation and Alternatives with Blue Tensor Spectra

, 2014
We study the tilt of the primordial gravitational waves spectrum. A hint of blue tilt is shown from analyzing the BICEP2 and POLARBEAR data. Motivated by this, we explore the possibilities of blue tensor spectra from the very early universe cosmology ...

Heart rate recovery and diastolic blood pressure ratio on the treadmill test predict an induction and recurrence of vasovagal syncope [PDF]

The Korean Journal of Internal Medicine, 2019
Background/Aims The induction and recurrence of syncope is a concerning situation that could be unpredicted in the vasovagal syncope (VVS). We investigated a simple predictor for the induced and recurrent VVS during Head-Up table-tilt Test (HUT) and ...

Cerebral hemodynamics in orthostatic intolerance with normal head‐up tilt test

Acta Neurologica Scandinavica, 2016
Orthostatic hypotension (OH) and postural orthostatic tachycardia syndrome (POTS) are well‐known causes of orthostatic intolerance (OI). In addition, there are OI patients who are characterized by the symptoms of OI and lack of abnormal findings in head ...

Tilt training as a treatment for reflex syncope: a multimodal approach!?

Frontiers in Neuroscience
PurposeReflex syncope is a burdensome disease with considerable repercussions on the quality of life. Tilt training is a therapeutic option, but evidence on this topic is scarce and outdated. Hyperventilation is oftentimes associated with reflex syncope.

Isoprenaline versus nitroglycerine in head-up tilt test

Indian Heart Journal, 2017
Background: HUTT test is used in evaluation of syncope. Isoprenaline and isosorbide dinitrate are used to increase the sensitivity of the test. These drugs act by different mechanisms.

Simulation of short-term pressure regulation during the tilt test in a coupled 3D–0D closed-loop model of the circulation

Biomechanics and Modeling in Mechanobiology, 2015
Short-term fluctuations in arterial pressures arising from normal physiological function are buffered by a negative feedback system known as the arterial baroreflex.

Signal-to-Noise Eigenmode Analysis of the Two-Year COBE Maps

, 1994
To test a theory of cosmic microwave background fluctuations, it is natural to expand an anisotropy map in an uncorrelated basis of linear combinations of pixel amplitudes --- statistically-independent for both the noise and the signal.

Age and the Head-Up Tilt Test Outcome in Syncope Patients

Research in Cardiovascular Medicine, 2015
Background: The head-up tilt test (HUTT) is a useful diagnostic tool for syncope. Objectives: We sought to investigate the outcome of the HUTT in syncope patients and identify the relationship between age and different hemodynamic outcomes.
