HRV and resonance-frequency biofeedback (Vaschillo, Lehrer)

What it is

Heart rate variability biofeedback (HRVB) teaches a person to breathe slowly at their own "resonance frequency", the pace at which breathing-driven heart rate swings (respiratory sinus arrhythmia) line up with the cardiovascular system's natural rhythm near 0.1 Hz, so that heart rate oscillations…

Format

• The protocol is a short, skills-based course of individual sessions with daily home practice.
• Published contraindications for RF assessment: heart rhythm driven by a pacemaker (the heart-rate signal then does not reflect autonomic modulation), and conditions that produce acidosis, kidney disease being the example given. Assessment should be postponed until the client can breathe comfortably…

Who practises it, and how they are trained or regulated

• BCIA offers an HRV Biofeedback entry-level certification (and a separate certificate of completion for technicians). Per a BCIA-accredited training provider's page: entry-level requires at least a bachelor's degree in a health-care or optimal-performance field, completion of a BCIA-accredited didactic programme, an anatomy and physiology requirement, mentoring logged with a BCIA-approved mentor (personal HRV…
• How change is thought to happen: the developers hypothesise that regularly producing these large oscillations "exercises" the baroreflex (the blood-pressure-regulating reflex) and makes it more efficient; they report increased baroreflex gain within sessions and at rest after about three months of twice-daily home practice, and regard the baroreflex account as the best supported. Vagal afferent effects on the brain,…
• Who may deliver it: HRVB is a behavioural method that trained psychotherapists and other health professionals deliver within their own licence; certification in the US/international system is through the Biofeedback Certification International Alliance (BCIA) HRV Biofeedback credential (see section 2). It is not a medical device treatment in itself, although the sensors and software are commercial equipment.

Evidence status, as the guide reports it

• Five visits in the 2013 protocol, refined in an asthma study; the authors describe it as a shortening of an earlier ten-session method. Weekly visits are typical in the research. A meta-analysis found no significant effect of number of sessions or weeks on outcome.

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• How do you and the practitioner understand what is happening, in spiritual or cultural terms? Is that a source of comfort, worry, or both?
• Does it use a device, heat, cold, water or a physical procedure? Has a medical professional checked that it is safe for you?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• forceful blowing or breath-holding.
• straining or breath-holding during tension.
• whether practice happens at all; review it first at every visit.
• anything suggesting an undiagnosed cardiac or respiratory problem.
• frustration or perfectionism; abdominal breathing turning into deep breathing.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
